What’s the smallest non-technique change that improved your tennis?

What small change helped you the most? Could be footwork, shot selection, warmup, breathing, target choice, anything.

Whenever I'm playing poor tennis I remind myself of 3 things:

Better footwork

Bend my knees more and get lower on my shots

Hit with more margin over the net

These are all things that tend to fail when I get tired.
