I agree with this. People ask me all the time what I thought about my experience at YC was like. And my answer usually comes down to being with the people. When everyone around you seems to be smarter, work harder, and be more driven, you really push yourself too. But, it was also a supportive community. Everyone wanted to see everyone else succeed. Basically, it was a good support group for those days (and there were many) where you just felt down in the startup dumps. The good news is that you don't necessarily need YC to have much of that experience. If you build a good network around you, with lots of hard-working and positive people, it helps a lot.
