I've found that my attitude and intent greatly affect my dreams. As said before, being confident is probably the greatest key, and it becomes easier to stay confident as you get results.

One thing that really sparked it for me was reading a thread and talking to a natural lucid dreamer and realising it isn't as hard as it seems. It's easy to get caught up in techniques and details, but when it comes down to it anyone can do it

ADA and meditation have greatly improved my awareness and recall, which I believe have really helped me, it's just a matter of finding what works for you
