Be an enzyme - a catalyst for change. As a slogan, I don't know if that's ever going to be right up there with Ich Bin Ein Berliner, or “I Have A Dream,” but there's a lot of truth to it.

You should pursue your passion. If you're passionate about something and you work hard, then I think you'll be successful. If you start a business because you think you're going to make a lot of money at it, then you probably won't be successful, because that's the wrong reason to start a business. You have to really believe in what you're doing, be passionate enough about it so that you will put in the hours and hard work that it takes to actually succeed there, and then you'll be successful.

We ought to be looking at business as a force for good.

Long-term sustainable change happens if people discover their own power.

In February of 1996, about six months after I created eBay, I started receiving a spate of complaints. Everyone was complaining about each other. I felt very much like I was a parent who had to adjudicate the brothers beating each other up.

I always kind of just went ahead and tried things.

I want people to be entrepreneurs, but I want them to do it for the right reasons, because they think they can change the world, because they think they have got something of value to give to the world. Not because they think they can make a lot of money.
