No it wasn't a nerve, sorry if it came that way. I refrain from using smileys on forums but my post should have started with one :).

I very much agree with you and see what you mean, went through some of these things myself (the post-30 part). Most vividly I came back to university as a student in my late 20s/early 30s (here in France most students are 18-25, and I was with the 18-20 in class). I know what you mean about the posturing and everything. But that's the beauty of age, I could just hang with the 'normal' ones according to my perception, and ¯\_(ツ)_/¯ the others. Made some very good friends regardless of the decade gap.

Currently at 34 in my phase "starting my own business", reigniting a dream I've sorta had since I was 12.

Totally agree with your last sentence. In fact I find that the best entrepreunarial wisdom/advice may come from the first century AD, or from 1903, 1937, 2016... Because the toys changed (tools, really), but the function (organizing some process involving value for human beings) is ever the same. On a personal level it's equally true, I am personally an adept of Stoicism, which isn't exactly new, yet incredibly suited to our present time imvho.
