Here's someone else who had something interesting to say. This had a huge influence on me when I read it in my early 20's. And nothing has been more true.
 

"Until one is committed, there is hesitance, the chance to draw back, always ineffectiveness. Concerning all acts of initiative and creation, there is one elementary truth, the ignorance of whichs kills countless ideas and splendid plans - that the moment one commits oneself - then providence moves too. A whole stream of events issues from the decision, raising in one's favour all manner of unforeseen incidents and meetings and material assistance which no man could have dreamed would have come his way.

Whatever you can do, or dream you can do, begin it. Boldness has genius, power and magic in it. Begin it now."
