One important thing.... if you live in the US  you must pass an FAA test to be rated and you need the rating to sell your footage.

Okay, the consensus seems to be that I am wasting my time because I am making  so little money. On the other had I am a photography addict so unless they have a rehab for it I'm in for the full ride. Because of this I will ask, humbly, for a mentor or mentors to get some help. Samples of my work can be seen  at www.flickr.com/photos/willied. I shoot with a CanonD5 MkII and I have been a serious photog for about 13 years. I qualified for iStock in 2006 but got quite active about 3 or 4 years ago. Right now I have 3099 photos in my port, have sold195 for a total earnings of $387.56. I have researched keywords extensively and I do not seem to have a problem there... that I know of. I know my earning are low so I am asking for someone... anyone... to offer some helpful advice. And quitting is not an option. Thanks in advance for any takers.
