- you are obliged to do it( includes the case when you become helpless and have no other option)
- you like do to it(includes the experimentation of doing the thing irrespective of whether it is right or wrong)
- you are so routinely used to doing it
Think about it, if a scientist keeps doing the same experiment getting the same result everytime, it is fruitless. Consider this, a spin bowler keeps bowling the same kind of ball. Well I dont think he will be effective at all.Similarly, it is important that we experiment just to give variety to life.
One of the major problems in experimenting is the part when you feel embarassed with your experiment.There always lies this part within your mind the "what others will think" factor(in short WOWT).This is a mental blockage and is very difficult to overcome. Every normal person succumgs to it at some point of the time or the other. I want to try smoking, I want to shave my pubic hairs, I want to shout in the library, I want to put a night out, I want to talk to a girl I saw.
Well I say go ahead and just do it without bothering about others. But remember, an experiment should be done with utmost safety considerations. It shouldnot harm you in the long run.
So what are you waiting for, just explore the world.Even this blog is an experiment. :)
