Managing Bitterness

It's very easy to become bitter. It's a slight difference from being jaded or cynical, as the former is a fairly value neutral description of a person that's experienced a lot of negative things, while the latter merely stands for the idea that human nature, particularly in power, tends to run to self interest. Bitterness, IMO, is the tendency to react to prior negative experiences by rejecting the possibility of later positive ones. Meaning, once one girl breaks up with you, a bitter man acts as if he'll never be happy in a relationship again. The jaded man simply realizes that break ups are part of life, sighs and moves on; while the cynical man wonders if relationships can exist for any reason other than self gratification by the two partners, and once that is exhausted by one or the other, they will simply discard their former partner.
