I do always find it funny when someone complains about someone playing a little slower. They will say something like, "slow playing is sooo boring". They are playing a big tourney, how fast do they think it will end? It won't end until the final table finishes, how ever long that will take.
To better practice at being patient, I will play play chips and set goals for myself. Like don't play a single hand until next level up no matter what I have. Then I will do the opposite sometimes play every hand. The most important one, always raise 3 times the BB, especially on the button. Good practice to raise with nothing, it gets you used to betting in position and not just betting with AA.
