Why the two individuals are different? Why we are behaving in our own way? Why sometime we become so complex to understand? Why we often behave irrationally? I believe that there is always a rational reason behind any irrational behavior. If you ask someone why we are different? May be the probable answer would be the structure of our genome is different. But I believe we all are different because we brought up in different environment. As for example a child from a broken family has different values or perspectives of life compare to a child who brought up in a joint family. Human brain has a peculiar habit; it interprets everything in its own way. The glass is half full or half empty is not only a perspective of an optimist or pessimist, but it also dictates by the situation in which the individual is in. Why someone becomes an optimist or a pessimist? Do we ever try to find the answer? I believe that experiences make all the difference. The experience is the key factor between an optimist and a pessimist. Most of the time we become irrational because we are forcefully taken out from our comfort zone. What is this comfort zone? Comfort zone is that virtual area in which every situation is in our control or we have an answer for every question or we have a solution of every problem. But when we come out from the comfort zone we do not behave in the way we generally do. So to control over ourselves we need to expand our comfort zone. But life is full of uncertainties, so ………….. and if, still we become irrational we have the “BRAMHASTRA” . You do not know what’s that? That is “Dude we are human being and we bound to make mistakes”. But the “BRAMHASTA” can be used at the end to win the battle. Hence before that we have to do the root cause analysis for our irrational behavior and also if we get an irrational behavior in return of our rational behavior still we have to analyze the situation. Most importantly we should put ourselves into his/ her shoe. Because you never know what is bugging him/her? So in a nutshell try to expand the boundary of your comfort zone to be rational and if you fail to be rational use the “BRAMHASTRA” at the end.
