When you write, read it back.
Not in your head. In your head it sounds different.
Read it aloud. Preferably to someone.
Most of the mistakes and awkward sentences will become apparent to you straight away. Some the person listening to you will point out.
It can be challenging. Not everyone reads aloud well. Not everything you will write will sound good. You have broad shoulders and a tough chin, you can live with it.
Happy reading!
