Today's quote is another funny one...or, well, it made me laugh anyway!

"(Professional) photographers are like hookers: at first we started doing it because we liked it and it felt good, then we kept doing it but only for our friends, and NOW we're still doing it but are charging money for doing it!"

EDIT:

Found another quote that I think kind of goes with the above one. ;)

"The photographer is like the cod, which lays a million eggs in order that one may be hatched."

--George Bernard Shaw
