no one’s upset by what you’re saying, you’re probably not pushing hard enough. (And you’re probably boring, too.) - Jason Fried

If no one’s upset by what you’re saying, you’re probably not pushing hard enough. (And you’re probably boring, too.)

Pass on hiring people you don't need, even if you think that person's a great catch.

Contrast (failure) that with learning from your successes. Success gives you real ammunition. When something succeeds, you know what worked - and you can do it again. And the next time, you'll probably do it even better.
