A Dream

Having a dream is not enough.  You must have the faith, belief and determination to fulfill the dream.  You must be willing to commit to it and change whatever you have to change about YOURSELF in order to see that dream come to pass.  You may have to give up some old lazy habits, some "free" time, some money and maybe some "friends".  Remember, you become what you associate with so make sure those associations are contributing to encouraging you in your pursuit.  Run the race to win, not just wear yourself out.
