There are always going to be doubters and obstacles to get to where you want to be. Nothing worth having in this world comes easy and nothing great ever comes without a sacrifice. The only person holding you back from being the person you want to be (a professional bodybuilder, a basketball player, a CEO of a Fortune 500 company, etc.) is yourself. You can either listen to people telling you it’s not going to happen or you can go out there and do the damn thing!
