In order to be a poker player...

[ScottySo]

I saw a post somewhere ( I beleive it was on pocketfives) recently saying something along the lines of "In order to be a good poker player you need to be able to take a $100 bill and burn it". The point is you have to be able to remove yourself from the money aspect of the game and just make +EV decisons. However I thought this was the total opposite of the truth. As a poker player you need to make sure all your actions are going to be +EV in the long run, which burning a money obv is not. What do you guys think of this quote, and are there other (better) quotes that fit this thread title?
