By doing your best and reaching your potential, by taking care of yourself first, you are actually doing good for everyone — for yourself, your community, society, and the world. The higher you climb and the more effective you become, the greater your impact will be. You can’t do much good if you are homeless, broke, and miserable. But you can do a lot if you are intelligent, capable, wealthy, and powerful. So if you truly want to make the world a better place, start with yourself. Become as good as you possibly can. Rise as high as you can. Climb the highest mountain. From there, you will see the world more clearly, and you will have far more leverage and influence to change it.
