As Descartes wrote, "I think, therefore I am" - it's what makes us human, creative, and, sometimes, miserable. The secret is to balance our self-contemplation with action.
We'll never answer all those questions or, I should say, we will answer those question many times and the answers will often change. If we don't have new answers, we aren't moving forward.
Do you agree?
