When I was in my 20s, I learned not only how to work hard but about the importance of focus.

I learned the value of hard work by working hard.

There's no escalators - there's only staircases to success. There is no substitute for hard work.

The only way to do something in depth is to work hard.

I just trust in God, work hard, and focus on executing.

Where people work and their environment is becoming more and more important, especially for millennials.
