Trust me, I understand the sentiment, and I'm thankful for the candor. I felt a bit robbed of the possibility, and understand there is some romanticizing/nostalgia going on. I do think that my stated reasons are worth it, however. Of course, I'd love to teach, and I'd teach anywhere if provided that opportunity, but I don't believe I understated the value that a graduate education has on continued access to academia as well as future collaborators. There is simply more opportunity with than without. Now are these opportunities financially profitable? Doubtful, but perhaps worth it nonetheless.
I've moved around my entire life, and I've grown accustomed to it. I don't have, nor plan on children. At the moment, my life will be what it is for the foreseeable future with likely opportunity for career growth in a field I am skilled in and tolerate. That's more than a lot of folks, I get that, and I'm not trying to look a gift horse in the mouth. If this risk proves an abject failure, It wouldn't take much to get back into the swing of things in my current career. If even remotely successful, I'd have my graduate education, new colleagues, hopefully some collaborators, probably some debt, and I'll probably find myself competing for comm. coll. teaching gigs, not get them, smile and thank them for the opportunity.
All this to say, I understand the risks, but I feel my values, attitude, and current place in life welcome these very risks.
