Remembering the things I did the last time to make my mix sound better.
Something doesn't sound right, what can I do?
Then it hits me. Do the thing that always works again, because I forgot to do it for the millionth time.
This mix sounds very noisy and there isn't much acoustic free space. Why is this? Nothing I do seems to be working! Right. I need to EQ to reduce my mids. And suddenly it fixed everything.
Repeat this for basically every mix I do ever.
