I try to manage my
poker games in a way as far as it concerns time (also BRM ) so as not to bother me and make me feel uncomfortable , very tired , not able to enjoy anymore poker . I choose the days and times to play , I see if I am going to play a tournament , freeroll or normal , for hours if needed .
Of course , sometimes things don't go as planned .
I also believe that some people are more energetic so after many hours of game are still more focused and tiredless than others , but this is part of the game . Most important for me is to have skill , patience , plan
