How did you learn to do it (if you had to learn it) and do you lucid dream all the time?

I am somewhat unusual in that I never "learned" to lucid dream, and I don't know that I ever do dream any other way.

This is clearly true, but if I ever get around to mastering lucid dreaming I'll probably just fly around, blow stuff up, and generally have fun before I start using it for anything reasonable.

That gets old far quicker than you'd think.
