work as hard as

"Just be willing to do your work as hard as you can with the ability you have."
- Jerry Seinfeld, writer and comedian

great passion

"Let go of this idea that you have to find this one great thing that is my passion, my great passion." 

- Jerry Seinfeld, writer and comedian

following your passion...

"I can't imagine how sick you are about following your passion… Find something you can do that would be great.  If you try something and it doesn't work, that's okay too.  Most things do not work.  Most things are not good." 

- Jerry Seinfeld, writer and comedian

Accept your mediocrity...

"Learn to accept your mediocrity.  No one's really that great.  You know who's great?  The people that just put tremendous amount of hours into it.  It's a game of tonnage." 

- Jerry Seinfeld, writer and comedian  

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
