The first part of the secret is ... To stay here. If you cant stick to this, then how can you stick to a lifestyle change?
Work out how badly you want it. Get involved in the site. Look at other diaries and let them inspire you. Challenge yourself to work HARDER than your friends burns. THAT'S the magic pill and it WORKS.
