Motivation is an extremely important aspect of lucid dreaming. Without motivation, why do it at all?

My favorite way is to look through other people's dream journals here. Especially in the Dream Gallery (That's where they keep the awesome stuff). Seeing the amazing things other people have done is really helpful.

As for beginner tips...

Always pay attention. Pay attention to as much as you can. Eventually you'll find something a little off, and you'll become lucid.

Do well, and keep at it!
