How to change your lifestyle dramastically for the better?!

Well you have to have a desire to be in shape and have energy, otherwise you'll just be miserable during your efforts. The motivation for being in good shape is usually compliments and attention from women, which you WILL receive when you're fit and healthy.

So basically it's on you, do you want the respect and healthy & exciting lifestyle that comes with being in great shape? Then do something about it. I always tell people asking about exercise to go to bodybuilding.com, they have everything, articles on diet and training, exercise demos, forums, supplement reviews, check it out.

As for the mental, you should find a new hobby, something that's deep. Maybe a sport you've never watched before or something complex like car engine building if you're into cars.
