Level of dedication

"When I was starting out, I used to sit down and write a couple of times a week.  And then, I was watching these construction workers go back to work, watched them trudging down the street.  It was like a revelation to me: these guys don't want to go back to work after lunch, but they're goin'.  That's their job.  If they can exhibit that level of dedication for that job, I should be able to do the same."
- Jerry Seinfeld, writer and comedian
