Giving up on adwords. The competition is just too close for comfort. I'm guessing the profit margins after the adwords cost is so small the marketer must do huge volume, have a product in the $100's, or some recurring service to make profits.

don't bid too high and always remember not all customer click the adword ads some might google it the thing with adword is just getting your site some exposure

Adwords is a ridiculous amount of trial an error. Don't expect to see a lot of profit starting out. Don't get discouraged. Stick with it.
