Nine times out of ten, failure is resorting to Plan B when Plan A gets too risky, too costly, or too difficult. That's why most people are living their Plan B. They didn't burn the ships. Plan A people don't have a Plan B...There are moments in life when we need to burn the ships to our past. We do so by making a defining decision that will eliminate the possibility of sailing back to the old world we left behind. You burn the ships named Past Failure and Past Success. You burn the ship named Bad Habit. You burn the ship named Regret. You burn the ship named Guilt. You burn the ship named My Old Way of Life.
