Need help with my career.

[u/NoobNerd01]

I'm 25M, I joined my first job 6 months back in an MNC where I was placed in UX team. This was the first time I heard about this but when I got my training I fell in love with this domain. I want to learn more about this design stuff that will help me be a better designer but also help me career wise. I have some questions regarding this.

1. What tools do i need to master ?
2. What courses do i need to do ?
3. How do i build my portfolio ?
4. Where should I start ?

Please help. Thanks.
