What we can or cannot do, what we consider possible or impossible, is rarely a function of our true capability. It is more likely a function of our beliefs about who we are.
Tony RobbinsIf you find yourself saying 'I can't do something', but you know it in your heart of hearts that if you do it, you're going to grow, you're going to be a better person, it's going to contribute to your family or to your kids or to something that matters, and you keep saying 'I can't do it,' there is no questionโyou must do it. You don't discuss it anymore. You just take immediate action... You do what's necessary.
