They say that an artistic medium is a medium to express and not impress (or that's what I read from a blog of a new generation writer). Not more could I agree with the sentence and especially the rhyme in it makes it sound very profound. But at the same time, I feel that the biggest reward for such an expression is when someone "get's it". Someone understands what you went out and expressed. Someone gets impressed with it.
As the hindu philosophy goes, "karm kar phal ki chinta mat kar" ("Do your work and do not worry about the results" - something my mom always says since childhood and I had written this down and pasted that note behind my computer in iitk and a few guys saw it and made total fun of it).
Maybe the same applies here - express yourself without any inhibitions. So much so for the goal oriented world.
