It's similar for me. I don't know anyone, especially myself that
   doesn't suffer from limited understanding. That's what drives me
   to keep putting pieces together, taking them apart,
   reconfiguring, etc. I assume everybody I meet has something to
   teach me: the more I disagree with them, the more they have to
   teach me. I may learn from them by argument or by listening but
   I'm determined to learn something from every teacher and every
   person I talk on (mostly online but often in person too) is my
   teacher.
