In fact, in the last job I had before coming to the White House - I remember this clearly - I was on maternity leave with Sasha, still trying to figure out what to do with my life, and I got a call for an interview for this position, a senior position at the hospitals. And I thought, okay, here we go. So I had to scramble to look for babysitting, and couldn't find one.

When you're really trying to make serious change, you don't want people to get caught up in emotion because change isn't emotion. Because change isn't emotion. Its real work and organization and strategy - that's just the truth of it.

Some kids have never seen what a real tomato looks like off the vine. They don't know where a cucumber comes from. And that really affects the way they view food. So a garden helps them really get their hands dirty, literally, and understand the whole process of where their food comes from. And I wanted them to see just how challenging and rewarding it is to grow your own food, so that they would better understand what our farmers are doing every single day across this country and have an appreciation for ... that American tradition of growing our own food and feeding ourselves.
