Tips on drawing hands?

Hands are currently the bane of my drawing existence , and I am looking for advice on how to draw them more efficiently, Any tips would be recommended and, of course highly appreciated!

Take a picture of your hands, draw them, look at your hands and draw what you need, google references.

I had a lot of trouble drawing most (if not all of) the human body, so I decided to start learning human musculo-skeletal anatomy. I found a site that really helped me out, not sure if it has what you want, but it's still a fun place to go to: http://anatomyarcade.com/
