Never forget the purpose of all the books and articles you read, all the questions you ask, and all the stress you put yourself through.
You’re not simply seeking understanding. That’s for the ivory towers. You’re interested in action. You want to make a mark on the world, not just to understand it. Stop taking consuming and start producing. Enough input; don’t forget to output.
“Every tree that does not bear good fruit is cut down and thrown into the fire.” Matthew 7:19 (NIV)
Your problem is that sometimes you understand the world too well. You see too many possibilities for action and you become paralyzed. Like Hamlet.
Never forget that the reason for your studies is to take action, leave a mark, and do something great and important and powerful. Realize that people less educated than you have taken action and had success. You can always maintain your input; in fact, you absolutely need to maintain your input. But the time has come for more output as well.
