What really matters when it comes down to being successful? It’s not motivation. It’s discipline. Anybody can give 100 percent at the gym when they feel like it. Anybody can do the work they need to do when they feel like it. But it is the people who are completely unmotivated and even repulsed by the thought of hitting the gym or doing the work – and do it anyway! – that are the ones who truly dominate in everything they do.
