Humanity has been around long enough that the chances are whatever the vast majority of us do today, it has already been done by someone else...when it comes to changing the way we look and feel that is most certainly the case. So...use that to your advantage - be inspired by those who have done and those who are doing!
Personally, I look at images and articles from www.simplyshredded.com on a near daily basis. Seeing photos of guys and gals who have been there, done that and ripped the t-shirt off for the world to see what they have achieved makes sure I don't reach for a doughnut - well...until Feast Day that is!!!
