If you're already 15 years deep into your career then I would say to suck the quant industry dry of all the money you possibly can with your expertise before you switch to something else that you'd enjoy. $1mm+ is no joke and a very very rare opportunity.

Don't be a sucker. If you must, take option #2 - get that $1mm, and then exit.

This isn't the most wholesome suggestion I've given, but given the harsh realities of the world and capitalism at large, you must protect yourself with money.

Form an exit plan, set aside a large cash reserve so that you technically never have to work a day in your life ever again, and then chase your passions and explore all the other things the world has to offer.
