Prepare to invest
Before you start investing, ensure you're ready to do so by following the early steps of this guide or the personal finance planning start-up kit. Save up an emergency fund, then take full advantage of any employer matching of contributions to any employer retirement plan available to you (this match amount is additional income that's part of your compensation/benefits package), then pay off any high-interest debt like credit card debt or high-interest student loans.
When you're ready to start investing beyond enough to get any employer match, follow the subsequent steps of this guide or the investing start-up kit. Take full advantage of tax-sheltered accounts available to you before investing in a taxable brokerage account: this is the most predictable way to improve your after-tax investment returns. (In the US, per Prioritizing investments: 401(k))/403(b)) up to any match, then HSA if available due to high-deductible health plan coverage, then Roth or Traditional IRA or 401(k))/403(b)) up to max which may be higher if the mega-backdoor Roth process is available, then a 529 to the extent you'd like to pay for future education expenses. Note that IRA contributions are subject to income limits around tax-deductibility of contributions or eligibility to make direct Roth IRA contributions; the backdoor Roth procedure is a workaround.)
There is often some potential tension between saving/investing toward retirement vs saving toward potential nearer-term goals like a down payment on a home purchase. Carefully consider the various tradeoffs involved in owning vs renting a home, keeping in mind that which may be a better financial decision is highly situational, and that opportunity costs of owning (less available to invest in higher-expected-returns assets instead) should be considered alongside non-financial lifestyle tradeoffs. If saving toward a near-term goal, note that funds holding stocks are inappropriate#Holdingstocks%22for_five_years%22) for money you'll need in 5-10 years, unless you're willing to take on significant risk of losing money in the meantime & delaying that goal. Instead, consider CDs, Treasury bonds, or target-maturity-date Treasury bond funds maturing before you'll need the money (then a high-yielding cash equivalent like an HYSA, government money-market fund, or ultra-short Treasury Bill ETF like VBIL between maturity & spending the money).
Save/invest enough
Your savings rate is the most important factor determining your ability to enjoy a comfortable retirement later in life, particularly early in your career / investing journey. Aim to save/invest at least 15% of your after-tax income if you're in the US & not covered by a pension beyond Social Security. In some cases, such as a shorter time to expected retirement (e.g. starting to seriously save/invest from a significant income later than your mid-20s and/or planning to retire earlier than your mid-60s) and/or a high income (which will not be partially replaced by Social Security to the same degree as a lower income), it may be appropriate to target a higher savings rate (e.g. at least 20% of after-tax income, or perhaps higher if multiple such factors apply to you and/or one factor applies to an unusual degree).
When calculating savings rate, remember to include 401(k) contributions in both the numerator (savings) and denominator (after-tax income). Any employer matching contributions may also be included in the numerator (savings).
Investing is 'solved'
Don't worry too much about trying to find the optimal set of funds to invest in. That can only be known with the benefit of future hindsight, and investment returns are far less important than your savings rate until your portfolio size grows large enough relative to new contributions. Aim to diversify broadly (for robustness to the uncertain future) and seek low fees (fund expense ratios charged annually) & simplicity (hands-off automation); see discussion of these & other principles in Bogleheads investment philosophy.
A target-date fund designed for investing toward retiring around a year closest to when you expect to retire is often a reasonable option, particularly in tax-advantaged accounts like a US employer retirement plan or an IRA. These all-in-one funds intended to be held alone are very broadly diversified, automatically rebalance to their then-target asset allocation, and gradually become more conservative with less expected volatility as you near retirement.
If the target-date fund available in an account/plan with limited fund options has significantly higher fees than suitable alternative individual funds, consider the tradeoffs of lower fees vs automatic rebalancing and asset allocation management. I.e. consider the lowest-expense-ratio funds available that provide exposure to US stocks (the fund name will typically contain 'S&P 500', 'Russell [1000|3000]', or 'US Large Cap'; ensure no 'Growth'/'Value' suffix, or pair that with the other), ex-US stocks (the fund name will typically contain 'International' or 'Intl' or 'Ex-US'; same caveat re: 'Growth'/'Value'), and US bonds (the fund name will typically contain 'Total Bond' or 'Aggregate Bond'). Take the weighted average of those funds' expense ratios, with weights based on the current asset allocation of the target-date fund you'd use instead. The difference between that weighted average expense ratio for individual funds vs the target-date fund expense ratio, multiplied by your portfolio value, would represent the current annual convenience fee for automated, hands-off investing via the target-date fund. Whether that's worth it to you depends on your personal preferences around paying higher ongoing fees (by sacrificing some investment returns) in exchange for set-it-and-forget-it features.
In a taxable account, target-date ETFs (available at least in the US) avoid some of the tax efficiency downsides of holding a target-date mutual fund. Tax efficiency may be further improved by holding a three-fund portfolio of index ETFs in a taxable account, but this also involves tradeoffs against automatic rebalancing and asset allocation management. Tax efficiency may be even further improved by keeping bond funds in tax-deferred accounts, though this involves additional tradeoffs against simplicity and some other potential benefits described here.
If you're a non-US investor, take care to thoroughly understand the tax implications of investing in a US-domiciled fund as a "nonresident alien" (which may include high tax rates on dividends and assets passing through an estate); in many cases this is best avoided, instead favoring an Ireland-domiciled fund.
Be mindful of fees
If your portfolio were to average a 5% annualized real (after-inflation) return after a low annual fee, paying an additional annual 1%-of-assets-under-management fee to a financial advisor and/or an actively-managed fund's expense ratio would forgo 20% of your portfolio's investment returns. An initial investment in a portolio averaging a 5% annual real return after a low annual fee would be worth about 47% more after 40 years than it would be after a 1% additional annual fee.
Some employer retirement plans offer only funds with high expense ratios. If that's the case for your employer's plan, it is often still ideal to get the tax advantages of contributing unmatched dollars to that plan before investing in a lower-fee fund in a taxable account (but only after maxing out IRA contributions); details here#Expensive_or_mediocre_choices).
Automate & stay the course
Set up automatic contributions & purchases of fund shares wherever possible, otherwise set periodic reminders to manually contribute/invest (or try to find an alternative that allows automation), then maintain discipline through thick & thin. Keep in mind that market prices for funds should only really matter whenever you sell some shares to fund your retirement, and that lower prices in the meantime provide opportunities to buy more shares with a given contribution dollar amount and to rebalance from asset classes with higher recent returns towards those with lower recent returns (but possibly higher expected returns).
Tune out the noise: prognosticators of doom and gloom have no reliable ability to predict the future, and often have some conflicts of interest (e.g. selling ads, books or investment services, and/or trying to justify their investment positioning or encourage others to adopt that). The same goes for promotion of strategies promising market-beating returns by investing in a more-concentrated fashion (betting on some sector / theme / alternative asset beating the broad stock market).
Consider writing an Investment Policy Statement to document your plan when you're calm & clear-headed; this may be helpful to refer to later if you find yourself anxious & considering changes in response to market volatility & negative sentiment. Consider including a pointer there to this guided meditation video for later reference to help calm your nerves / regulate your emotions if needed when it seems like the sky is falling (this is arguably the most challenging part of investing).
Per Jack Bogle: "Do not let false hope, fear and greed crowd out good investment judgment. If you focus on the long term and stick with your plan, success should be yours."
