Well, it is unlikely that you will be able to make enough money off of it. I am speaking statistically of course...
Code
Statistics show that for a photographer in 2002 the average annual salary was $24,040. The lowest 10% earned less than $14,640, the middle 50% between $17,740 and $34,910 while the highest 10% earned upwards of $49,920. For a photographer employed by a newspaper or periodical the average annual salary was $31,460, while in other professional and scientific services the average was $21,860.

I'm not saying this to discourage you, just saying it to really show that if you want to make it as a photographer - you will need to try reaaalllllly hard. Or do it as a hobby / side job.
As far as my pet peeve....
I hate really "artsy" pictures. Things like "I took a picture of a cardboard box and the lighting was kinda shitty...but made it black and white so now its really damn cool"
Having gone to an art museum a few days ago, I found things that really grind my gears. A small square on a large canvas. How exciting. But that picture was getting the majority of attention from the crowd.
However the picture of a large, incredibly detailed and well presented cityscape got no glances. I guess looking at it just because it is weird is one thing, but actually saying that the square took talent / skill / time is comical.
I know a lot of photographers who make over $50K/year, and some even who make over $100K.
Depends what you are doing in the photography business.
