Sometimes, I put the full force of my intellect, persona, charisma, or will behind doing such trivial things. I've learned how to solve a Rubik's cube (and I'm actually starting to understand why the moves work) and I can solve it in under five minutes. I have taught groups of students to do things I myself did not know how to do (partly just for the fun of it and partly just to prove to myself that I am that good).
Yet I can't just walk across the street to the bar by myself, much less talk to anyone there.
