Everyone falls off the wagon at times, but it's not the fact that we fall off but the fact that we get back on, that counts. When you want to come back after time off, think about how far you've already come. Even if you gained back weight, or maybe gained back all and then some, you've still never gone completely back to that old you. You STILL are in the fight to be healthy, and that has to count for something!
If you follow this secret, you won't look at getting/staying healthy as a chore but something that is fun and makes you happy.
