Confidence and determination are in direct relation with action and the results of those actions. It's obvious, the more lucid dreams you achieve, the greater your confidence grows, therefore allowing your expectations and beliefs to be met. Many stop at this last part, thinking that to achieve lucid dreams one only needs to believe he/she can do it. But that's only half of the equation. What gets us to that point, were what we believe ends up being what ultimately happens, is a result of the actions that we make every day towards that goal. This also applies to naturals. Maybe they're not aware of what they're doing, so to others it seems as if they're doing nothing. Maybe they don't follow any specific technique, but they do something in their own way that delivers results.

I can say I can do anything as long as I believe it, but if my mindset doesn't correlate with my actions, then as much as you might want to believe you can do something, it won't happen.
