I know this thread is a little stale, but I'll respond anyway.

1) Become more proficient at having LDs

2) Increase control and duration

3) Learn to shapeshift

4) Gain mastery over space and time

5) Hook up with forum members and exchange information that can be verified in the waking world.

6) Find some way to reconcile what happens in lucid dreams to science. Perhaps through quantum physics.
