(For non players, this means that you are a winner at lower stakes, say $5/10 - but a common trait is that you become bored with that level because the most you can win each day is ~$1000-3000. As you move up levels the play is a lot harder (exponentially so). Players like this guy crush the small levels and think they are good enough for the higher levels, and just end up losing it all - often blaming their luck in the process. If you look at his chart, you will see that he won it all playing medium stakes, and lost it all (in a lot shorter time) playing high stakes).
