Don't let yourself think about it too much. Just jump right in! You can always rationalize putting it off till it is convenient... and it never will be. Start right now
and then just force yourself to keep going. It's like anything that you don't really want
to do: that first step is always the hardest. Rip that band-aid off. Just do it.
Okay, I am all out of cliche encouragements... but I meant them all.
Good job on the 40 pounds!!! That's awesome. How was your vacation?
