Being an entrepreneur isn't really about starting a business. It's a way of looking at the world: seeing opportunity where others see obstacles, taking risks when others take refuge.

Nobody's going to go home for a year and come back. Nobody could ever enforce that. Nobody in their right mind would ever try to do it.

After hard work, the biggest determinant is being in the right place at the right time.

When it comes to public school education, we have been unwilling to measure our results. We've been unwilling to pay based on performance. We have tenure where, even if you can't teach, you can't get fired. We've been unwilling to invest in new schools.

If you really believe that you're making a difference and that you can leave a legacy of better schools and jobs and safer streets, why would you not spend the money? The objective is to improve the schools, bring down crime, build affordable housing, clean the streets - not to have a fair fight.

Even though New York is the safest big city in the nation, there are still far too many illegal guns on our streets. Nearly all of them arrive from out of state - and most are sold by a small group of rogue gun dealers who refuse to obey federal laws.

Government is dysfunctional.
