I have a post-it note pad stuck to the top of my monitor. Before each session I peel one off, then I take a post it note off and write the focus point for the session on it. Some of my notes:

- Don't marry pf monsters
- Range range range
- Position position position
- Plan the hand before you VPIP (based around likeliest flop)
And my latest one: nits don't bluff.
