"If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus; and you must not stay there, you must go beyond them."
Ok. So maybe you have had a bad day. Dont beat yourself up over it, but dont let one bad decision send you spiraling out of control. Grab those running or walking shoes and get back into it. Get back to making decisions that improve your health and your happiness. You are who you chose to be.
