The cards don't care what your goals are.

Your emotions affect your decision-making abilities; for those with faith in the longview it may only occur on a subconscious level, but it still happens.

Maybe your confidence in your reads rises or falls with monetary success... maybe your discipline in the blinds wavers after a run of bad luck... maybe you fall into the trap of feeling "due" and you play marginal coin-flips unnecessarily... maybe you're just tired.

It could be any number of more subtle things for any particular player. It's foolish to consider yourself immune to such leaks.

If a break leaves you feeling refreshed and positive after an extended period of feeling negative and ultimately resigned, it's not only +EV, it's infinite EV, since you should always, and only, play in that state of mind.
