Making drawers seems to be a frustrating task for a lot of people. I did a bunch of them and found I had some problems. I've read some good books on the subject, but there's nothing like seeing it done.
I found this video at my local library, and it's one of the most inspirational videos I've ever seen: http://www.amazon.com/Dovetail-Drawer-Frank-Klausz/dp/1561587044
It was made in 1984, but the author is still doing presentations and putting out videos on YouTube (search on his name). There are also a few skills he has that he doesn't really discuss, such as the ability to saw a perfectly square and vertical line without a guide (of which I am envious), but in general he shows that drawers don't need to be challenging with just a few simple steps.
