You can train your eyes to find what’s wrong or what’s working. Both are skills. Pick one to practice.

Fault-finding and strength-spotting are both learnable, and both get better with repetition until they run automatically. Whichever one you have practised more becomes the way the world arrives to you. Neither is useless, since you need the critical eye to fix things and the other one to keep going. The problem is only ever having trained one of them.

Practise the weaker one this week. If you default to criticism, name one thing that worked after every session, shift or argument; if you default to optimism, name one thing that needs fixing. Be specific, because vague praise and vague complaints both train nothing.
