Think of it this way: If you got a flat tire, what would you do? Change the tire? Or get out of the car and slash the other three tires? No! Get back on the road. Don't dwell on it; don't beat yourself up. That gets you nowhere.
People believe practice makes perfect, but it doesn't. If you're making a tremendous amount of mistakes, all you're doing is deeply ingraining the same mistakes.
I've always believed fitness is an entry point to help you build that happier, healthier life. When your health is strong, you're capable of taking risks. You'll feel more confident to ask for the promotion. You'll have more energy to be a better mom. You'll feel more deserving of love.
