are many factors by which poker players make mistakes, for example, SLOWPLAY, trying to make bluffs on a table that do not know the players, etc etc ... really are many factors, the losses teach more than the victories, good luck

Characteristics of an anxious person.
Meditation and self control is the key to that friend.
I would say not knowing when to quit. Most of us have been there. Some bastard makes a terrible play but luck's on his side and he takes your stack. Then 5 minutes later it happens again. You realize that he chances of a 3 outer happening twice in back to back showdown is tiny so you start to fume. You think you can beat luck by playing more. You cannot.
Before you know it, you've put yourself in a hole difficult to climb out of and you have given away weeks of winnings in one session cuz you cannot stop.
Playing a mediocre hand for an all-in is definitely not a good idea either.
