Perhaps some of them were simply following what their parents had done. I understand the need many of us (unfortunately probably both of my children) were born with to buck the "system." To find out for ourselves what we believe.
Do yourself a big favor and really explore. Throwing everything you know out just to let the space fill in with yourself is narcissism. Instead of throwing things out, explore if you really believe them or now.
"I had to go all the way to Boston to figure something out ..."
I'm not the one who originally said it, but I could have. I grew tired of the "establishment" and I took off on my own. I went somewhere that I didn't know anyone. And I learned (not just because I was in grad school).
