Agreed. I'm quite happily pedestrian, and I've met too many people who "went deep" only on a few subjects but were very boring people unless you talked to them about their chosen subjects. Some of my best friends are boring from an economic standpoint because they're poor. But they're wonderful people and I wouldn't trade them for any of the learning I could get from someone who makes more money.
I think Hunter S. Thompson's advice for young people is much better, because in it he makes the point that anyone seeking to give you advice can't possibly know enough about your situation to give good advice.

If who you are is pedestrian, don't hesitate to be the most pedestrian you can be.
