The mere fact that you aren't deriving earth-shatteringly new heretofore unknown insights does not make the usefulness of contemplation null-and-void.

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. I wonder if then I'll feel like I need to spend less time while awake on time-wasting activities.

Do you know of any good tutorials? How did you learn to do it (if you had to learn it) and do you lucid dream all the time?
