Alrighty, as far as I know theres not a thread on this already.

I'm at a stage where I've had heaps of fun so far in lucid dreams, and am ready to begin looking at more practical things to accomplish.

So I'm wondering, what is the most beneficial thing that people out there have accompished that has benefited their waking life? Solved a problem, had an idea, gained information, conquered fear, etc? You tell me.
