A bit OT, but I thought it would be fun to share.

Someone on linkedin asked this question in an entrepreneur list. What quotes inspire you the most?
The first is a George Bernard Shaw quote:

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.

This makes me think of entrepreneurs as “unreasonable men”. We try to get the world, or at least our chunk of it, to see the value in what we do.
The second is a Robert Heinlein quote, from one of my favorite books:

We don’t expect kittens to fight wildcats and win. We merely expect them to try.

This makes me think of how, as a small company, you have to compete. There are big mean cats, and if you want to survive and thrive, you have to be able to handle this.
One more that comes to mind is a Tom Clancy quote

If you are going to kick a tiger in the ass, you’d better have a plan to deal with the teeth

Basically, once you get traction, once you make an impact, the big guns are gonna come for you. You need to be ready.
So to see who else has some good ones, please, by all means, let me know your favorite inspirational quotes and sayings.
