Every person throughout his or her life tries to pursue some kind of ideal. Everybody sees different ideals. Some want to make big money. Others want to make a career in science hoping to make a unique discovery for mankind.
And things get to me sometimes, because like anyone else I, too, feel disillusioned at times. And then there are the insults... But I can endure all these things if there is a goal that is much higher than engaging in some kind of personal vendettas. Even exhaustion I can endure.
