An analogy would be to see yourself as a spider patiently waiting for something to fall into your trap.
You use your patience to wait for high quality hands. When you hit the nuts,, and you have an opponent who is happy with their hand, you try to maximize your lkely return.
That's the upside.
Many times, lady luck neither smiles nor frowns on us. She simply ignores us. Here discipline to wait it out, and more importantly discipline to not lose a lot of money on second best hands because you have grown impatient , is what earns you your pay check. Losing a lot less than the next guy, when the cards go against you, is just as important as winning a lot when the cards are hot.
