Here's your ton of bricks
“You know you need to take better care of your health. You keep waiting for some motivation. Here's your ton of bricks.”
Exactly what are you waiting for? Heart attack, diagnosis of diabetes, for the scale to actually break when you step on it? You're going to have to find the motivation inside of you. You have to decide that THIS is the moment. Not tomorrow, not next week, not next month, and not the next time you DON'T have leftover cake in the house. Make a list of how your life will be better if you do make some healthy changes. Make another list of how your life will likely be if you don't make changes. Pick the list you can LIVE with.
