What separates mentally tough players from everyone else?

[Bawse]

I think mentally strong players, especially in tournaments tend to run deeper, while in cash games that same resilience helps you handle wild swings and, ideally, crush the tables.

What do you think? What really separates mentally strong players from the rest?

I think one of the major thing that separates them from every other player is the state of their minds. These players have been able to train their minds to the fullest.
