How often I have found that we grow to maturity not by doing what we like but by doing what we should. How true it is that not every 'should' is a compulsion and not every 'like' is a high morality and true freedom.
Taking time to sit back and watch and think about what you've seen is important. Traveling did a great deal to me. I found that when I travel and just sit in the corner and watch a million ideas come to me.
