It may sound funny, but record everything until you get used to it.
It’s like pictures. “Back in the day” you had a roll of film that gave you 24 or 36 pictures, and it would cost you $15-25 US to develop all those pictures. As a result, people were stingy. They were careful to line things up, and make people pose, or whatever. You got one, maybe two shots of a given situation, and you waited days or weeks to see if anything was any good.
Now, we have digital cameras. You can blast out 150 pictures in 2 minutes. Look at them right away and delete and retake until you get the good one. Shoot 100 quick shots of an action scene and pick the best couple to keep. It’s all free. Take a thousand if you like. It costs no more than taking five if you delete the crappy ones.
Same thing. Record for 10 minutes every time you sit down to play. Listen back to it shortly after. Keep it or delete it. Keep one a week so you can track your progress. It doesn’t matter. Just whatever you don’t want and it costs you nothing.
Think of it that way. Record everything and trash most of it. The more you do that, the less it feels like OHMYGODIHAVEONECHANCEOGETITRIGHTDONTFUCKITUP!
