Every one does KH but hard work always pay,just like your hard work. I am successful (I can say that to my self) commercial photographer, it took me a year of publicity and hard work to get my first commercial assignment. in that first year i had to make do with photographing weddings and parties. it was in one of the party when i was offered an assignment to photograph shirts for the company catalog. And I haven't looked back since then now I get work from all over the world. So don't loose faith in yourself keep pushing what you believe in.
