Uncertainty

What if your are the only one?

I have a few questions.

Should one do something only when one is ensured that he will do it well? Should one paint only if one is certain to create something beautiful? Should one exhibit at the unique condition people will attend the exhibition? Will one come to an exhibition if he is guaranteed to meet with acquaintances?

What is the drive? What pushes us beyond the scare of the unknown? Is it the certainty of the result or the force of one's conviction that drives us through the realm of uncertainty? But how can we measure our own motivations? How do we know if it is sufficient and powerful enough to get us through unfamiliar grounds?

Could it be that our motives are correlated to that of our own interpretation of reality? Thus, does our ambition depends upon what we perceive to be true and what we make of it? Headach anyone?
