Give yourself plenty to care about, but not so much that caring is impossible. Be selective, seek balance, and live well.
Bring the energy of your purpose to the surface, and with it you can do beautiful things.
Go with what you know at the moment to be optimal, and then add more fortuitous choices as time goes on.
See your task not as addressing an array of negative challenges, but as achieving a single positive outcome.
Once you are speeding along with the momentum of achievement, don't let that momentum go to waste. Make more good use of it.
