nice post. i think it was tommy angelo that pointed out that the irony of all of this is that when you are tilted is the time that you are least able to perform anything close to an objective analysis of your mental state. this is why learning to quit is the nuts, you don't have to be 100% raging and ready to smash your mouse to bits - if you are even slightly tired, bored, frustrated, agitated etc etc then end the session. the tables will always be there. don't keep on grinding and let it swell up to the point where you are completely drooling and too emotional/stubborn to quit the session.

i'm speaking for/to myself here.
