I don't think any of us have the answers to everything. There's no human being on earth who fits that category. So why wouldn't you ask for help? Why wouldn't you run ideas by people that you respect? Too many young people cast around trying to figure out what the answer is themselves, because they're afraid to come back and say, "I'm not sure I understood you," or "Could you give me a little more information about what you need?" Just do that. It saves you time, it saves your boss's or mentor's time. And it's a great lesson to learn.

[Independent experts] have looked at my plans and they've said, OK, if we can do this, and I intend to get it done, we will have 10 million more new jobs, because we will be making investments where we can grow the economy.

I've said that we're going to produce real results for the American people because so many Americans feel left out and left behind, they think the economy has failed them, they think our government has failed, they can't stand the gridlock and dysfunction in our politics, and I'm determined to produce more good jobs with rising incomes, and deal with all of the concerns that families have about education, college affordability, student debt.
