Government should not tell you what to do unless there's a compelling public purpose.

The public is upset. If they haven't lost their job, they know somebody that has. If they haven't lost their house, they know somebody that has. What do you do? When something's wrong, it's government's job to fix it, it must be government that's responsible for causing it.

Getting the job done has been the basis for the success my company has achieved.

When I came into office, people said, 'Billionaire? How do they live? What do they eat? How do they sleep?' Today, they see me on the subway coming uptown. A couple of people say hi, some people smile and nod. Some people just sleep. It's not an issue.

If you don't encounter setbacks in your career, if you don't have doubts and disappointments , let me tell you, you're not dreaming big enough.

It's no fun to protest on an empty stomach.

I don't believe that government is good at picking technology, particularly technology that is changing. By the time you get it done and go through democracy, it's so outdated.
