Conundrum

I have always been plagued by many conundrums, however, this seems to encompass many, structuring a reoccurring theme. Though, many believe that introductions should not include questions, I find it hard to do anything else when I hold more questions than answers.

So here goes: What distinguishes the difference between an artist and a person who paints? One who plays an instrument and a musician? A person who is able to write well and a writer? What is the qualifying factor that sets in stone which end of the fence you reside?
Do you care about people or are you a humanitarian? Does it lie in intention, in effort or in the end product/situation?

I suppose the deepest problem I have is that I hold too many questions such as these, concepts seemingly paradoxical, however, immeasurable, forcing them to be nothing more nor less than one heavy conundrum.
