It’s no surprise that many of the greatest investors are or were at once great entrepreneurs. Because as investors, generally, most often, if not basically always, you’re investing into businesses, enterprises and capital markets. The better you understand business, the better you’ll know what a great business is, and what a great investment is.
This is not to say, you have to be an entrepreneur to be a great investor. However, being an entrepreneur and understanding how to build a business, will help you greatly as you choose which businesses to invest in.
