When I first started I felt the same way. I was overwhelmed by how beautiful some of the photos were and how the banners were created. I wanted my pictures to look like that. I felt waaaaaay over my head.
I did not think about it for some time and then it took some time until I got interested again (and a better camera) then I began to progress a bit, little by little. I am working on it but I will not going to ever be an expert Photographer. I just don't care enough. I figure if I learn something every year then if I am given enough time here I will get better.
Don't make ATP a job, do what you want.
