I agree it's a bit confusing at first but by the end it really gets to the point about finding happiness in your life purpose, being a might force of nature, and not giving in to selfish whining and complaining that just gets in the way.
I found some new ones today that helped me get closer to a new domain for my new site. I really love that last one:
"Well done is better than well said." Benjamin Franklin
"Inspirations never go in for long engagements; they demand immediate marriage to action." Brendan Francis
"A barking dog is often more useful than a sleeping lion." Washington Irving, adapted from a verse in the Bible
"The vision must be followed by the venture. It is not enough to stare up the steps - we must step up the stairs." Vance Havner
