One friend of mine did the same, here in France: high level degree, but only one year working in front of a desk. He totally switched to a sailing instructor job. As a computer engineer and sailor, that's really appealing me, but my skin wouldn't bear it. I know he's 100% living during the day, I know I'm making mouldy on my chair...
I can relate 100%. I have a good friend who quit his desk job in finance to go to Marine OCS. He runs around in the woods, climbs on mountains, and sleeps on the ground everyday. This might be dumb, but I feel like he's already done more with his life than I ever will.
Anyway, that's why I'm supporting my job : that mental and physical reboot through sailing every week-end became essential to me. Finding your own weekly brainwasher is a fair compromise !
