“The only thing that I see that is distinctly different about me is: I’m not afraid to die on a treadmill. You might have more talent than me, you might be smarter than me, but if we get on the treadmill together, there’s two things: you’re getting off first, or I’m gonna die. It’s really that simple.” - Will Smith

"You have to work for it." ~ Brian Wilson

I like this paragraph from the linked article:

"I think two things apply here: single-mindedness and massive effort. To truly excel at something, we need to be very focused. We can have different things we are striving to succeed with, but when we are working on one thing, we should be completely focused on it."
