You don’t have to completely change the world to “do good.” But you should always try to provide real value. As Musk has said, “If you make something that has high value to people…and frankly, even if it’s something, if it’s like just a little game or some improvement in photo sharing or something, if it has a small amount of good for a large number of people, I think that’s fine. Stuff doesn’t need to change the world just to be good.” Look for a positive cause in the work you do. No matter how small, it will help you be more motivated.
No matter your goals are in life, adopting the habits and mindset of Elon Musk will help you get there. The extra effort you make today will have a big impact tomorrow.
