"I spend basically all my free time reading, engaging in self-improvement activities, and plotting for my eventual world domination (heh)."

While withdrawing and plumbing the depths is an important and valuable experience in itself, it's worth keeping in mind to that all of the reading, self improvement, and self education receive their greatest value from taking that knowledge and living.

A fun evening is an end in itself sometimes. Though, not always! It's about balance.
