The best lessons are usually learned from failure. You musn't beat yourself up if you fail - just pick yourself up, learn as much as you can from the experience and get on with the next challenge...The brave may not live forever, but the cautious never live at all.
Richard BransonNo matter where my travels take me, my day starts with a good work out, preferably kitesurfing or tennis. Exercise puts me in the right state of mind for the day. Dedicating time in the morning to exercise your body will make a big difference when you have to focus your mind on the day's work.
