Two things I found made poker seem SOOO much easier:

1) Very very rarely play OOP.

2) Very very rarely call a 3-bet.


If you dont put yourself into shitty spots, poker becomes a lot easier. I know you just said that, and I know everyone says it, but they really are spots that are hard to stop getting into if you're not used to it. I guess I'm just reinforcing that these two things really are important to work on.
