Everybody tells you, "Follow your passion, follow your passion."

There are a lot of things I am passionate about. (But) the things I ended up being really good at were the things I found myself putting effort into. A lot of people talk about passion, but that's really not what you need to focus on. You really need to evaluate and say, "OK, where am I putting in my time?"

Because when you look at where you put in your time, where you put in your effort, that tends to be the things that you are good at. And if you put in enough time, you tend to get really good at it.

If you put in enough time, and you get really good, I will give you a little secret: Nobody quits anything they are good at, because it is fun to be good. It is fun to be one of the best. But in order to be one of the best, you have to put in effort.

So don't follow your passions. Follow your effort.
