Rational vs Irrational thoughts

Personally, I think a successfully life is lead by mostly irrational thoughts and behaviors rather than rational thoughts because we as human beings, are subject to senseless actions without mental clarity. We always try to look for new things and improve the present condition. This crave for advancement and evolution drives us to irrational thoughts and maybe even an endless insanity for improvement. We are always trying to overthrow existing rules and making new ones in which we may break again. Even if there exists some rational thoughts in oneself, these thoughts are ultimately overcame by irrational actions. The society is always on the edge of evolving and trying something new, which is why there are mostly irrational elements in people's life.

In my life, I have had many irrational thoughts in which I acted against my self-interest. An example is when I decided to jump off the shallow area of the pool even thought I knew I might injury myself by doing so. In this attempt, I ignored the "no diving" sign and even went against my own self-interest. I think the reason for this action was because I wanted to try something "new" and therefore chose to ignore the rule by putting my safety at risk. To think about it, diving into the shallow area was really a dumb and irrational action.
