1. Read biographies of people who did it. (Re-read those books sometimes; you'll know when.)

2. Read business books by people who consistently lead/advised at that level.

3. Find your philosophy. (Hint: this happens within, in your inner world.)

— You only need two or three great books in each category to really get going. Date of publication doesn't matter much; try to vary across backgrounds and decades, centuries.

4. Exercise a minimum on a weekly basis.

5. Eat well. Sleep well.

And train that voice within to become a perfect friend. (Funny to think you only have to will it to get that in life, just… inside.)

That's the TL;DR.

The rest will be self-evident on your journey, and involve a lot of luck. But if you're like most people, were you to reach a few % of that wealth, you'd probably stop right there and no longer worry about money, for the rest of your life. Incredibly few have the will to 10× that, then 10× again, because it's exponentially harder and comparatively useless.
