I really hope I'll be slim and happy one day - will it happen?

Answer

This life is not a rehearsal - we are only given one shot at it. One shot to become the person we really want to be. One shot to eat well, get our weight down to where we want it to be. One shot to learn as much as we can. One shot to improve our lives and the lives of our family and loved ones.

Don't leave your life behind without knowing you gave it your best shot.
