What’s a good way to become a better investor?

Warren Buffett: Read everything you can. I read every book on investing in the Omaha Public Library. Fill up your mind with competing thoughts and decide what makes sense. Then jump in the water and start investing real money, rather than a paper portfolio. The difference between investing real money and is the same as reading a romance novel and actually dating. There’s nothing like experience. The earlier you start, the better.

I read a book when I was 19 that formed my framework ever since. You have to read a lot in order to be able to recognize which ones jump out at you—and then do some investing yourself.
