I hardly strive for perfection or do my best, I’ll do better next time is my mantra (as there is a sense of dissatisfaction gnawing somewhere deep within and never a fulfilment). It is the mental thing, I just can't discount my limitations when I imagine myself doing something, it is only when the actual work starts the limitations come to the fore stifling even my thinking or the thought process and leaving me inactive. Sometimes, I stop making effort to do it again (if the degree of disappointment is very high), otherwise I just do it the way I can and leave the rest (it is very difficult for me to get out of the 'self-pity' zone if I enter one and I harass a couple of dear ones, so I've to be careful I don't slip into it).
Basically I feel I've turned out to be a happy person. I don't feel I require any special conditioning to remain like that (some weird chemical composition in the brain maybe).
Once in a while I do get lucky and achieve near perfection as in the snap below:
I clicked it sitting in an auto-rickshaw in a traffic jam. Since then I have tried hard to capture fancy number plates (to make a series). But, has never come this close.
