Go for it! And, let us know how you do. If the talent is there, so are the bucks if that's what you want.
Some of us are into stock because that's what we do and like an addiction can't help it, some who have created a niche and are making the bucks and gain the recognition, some because it's a hobby, and some just for the appreciation that somebody used our pic for something.
And then there's fine art. Anything and everything on earth has been photographed, but nothing has been photographed til it's been done thru your eyes. That's what makes it different.
Go for it and good luck
We'd probably all be taking pictures anyway,
