A good writing practice, really a good anything practice: write the thing, edit, and then make it 10% better.
There’s always a way.
Put a little more in, or take a little something out.
Smooth out the phrasing. Adjust a word or two.
Maybe you aim for 10% better and you get 2% better. But you might get 15% or 20% better.
Works for more than just writing.
