I don't agree with twizzybop's post about avoiding going on tilt. It is just not true. Being "emotionally intelligent" keeps logic pumping and emotions suppressed enough that they don't control your thinking. This is something I learned in college. It also takes practice and acknowledgment. I could go further into the concept; but, it is beyond the scope of this thread.
Working somewhere you hate until you find a new job is an example of not letting your emotions overpower your logic. It's done all the time. Remembering your goals is a way of overpowering the emotional response to performing an unwanted task that needs to be done; in order to, complete your goal.
In poker, listening to your gut and making a call is logical. But, to make a foolish call out of revenge, anger, etc. is emotional which is the worst way to play.
Also, taking a break from the game shows that you can't handle the pressure of losing. It's a weakness that will be exploited by better opponents; however, if it's the only way for someone to keep their emotions in check- so be it. But, I would find a better way to cope.
Thinking emotionally is dangerous. Not only in poker, but in real life. Getting arrested; getting in fights; buying something you can't afford because you want it; are, some of the signs of poor emotional intelligence. Poor emotional intelligence, in general, will lead to mediocrity- at best.
