Seeking advice on trade journaling

Hello everyone, I'm trying to improve my trading. Lately, I've been seriously trying to keep a trading journal again, but sometimes I don't know what to focus on, other than just where I entered and exited. I'd like to know what most of you in the forum record to make it truly useful for review and self-improvement. Do you have any recommended guidelines or templates? Especially regarding the psychological state before and after a trade, how should I record it to make it beneficial?
