How do you think for yourself?

My grandpa Ted once told my brother Lance not to get too excited about computers because he didn’t think anything would come of them.

Boy, was grandpa wrong!

How do you persist under the watchful eye of parents, grandparents, teachers, and other “adults” in your life? – when they can clearly be wrong. How do you follow your passion and instincts when it’s sometimes an uphill battle against the “wisdom” of your family, friends and well educated people?

How do you think for yourself long enough to actually make a difference?
