When you're sure you're on the right road to success you don't have to plan your journey too far ahead.
Don't burden yourself with doubts and fears as to the obstacles that may bar your progress.
You don't need to know all your answers in advance. Just have a clear idea of the goal you want to reach. You can only take one step at a time.
Once you muster up the courage to begin, you'll find the courage to succeed. It's the job you never start that always takes the longest to finish.
