Don't get roped into talking about something that you don't really have passion for, and don't get roped into something you don't have expertise in. Why should somebody listen to you? If you're going to take somebody's time, you better deliver.
Tony RobbinsThe truth of the matter is that there's nothing you can't accomplish if: (1) You clearly decide what it is that you're absolutely committed to achieving, (2) You're willing to take massive action, (3) You notice what's working or not, and (4) You continue to change your approach until you achieve what you want, using whatever life gives you along the way.
