Imagine that all those ideas, opinions and habits in your head get their voices and turn into people. Tell us about "the guy in your head" you like the most and/or the guy you hate/fear the most.
The guy I love is the big dreamer who asks "What's the worst that could happen?" with a smile. The guy I hate is the one who holds onto grudges and fights imaginary arguments in his head. The latter is a huge waste of time and energy, methinks :)
