Seize the moment, friend! What you can do NOW with that 10% slice will never exactly be on your possibilities map again.

If you can retire at 40 having lived your 20s/30s to the fullest then game on, but it would be crazy to sacrifice that time when you are so free and full of energy otherwise IMHO.
FWIW I am fortunate enough to have really enjoyed by earlier years and be mostly retired in my early 40s.
I should point out that it's cheaper to travel when young: Back then I stayed in a tent in the desert and in a friend's room near Amsterdam. If I did the same trip today, I'd have my family in tow, and would need more comfortable accommodations.
I should also point out that startup equity is not retirement savings. Selling 10% of your equity, investing most of it, and then doing something that you won't be able to do when you're old is a very wise and mature decision.
After 40 you've already made many of your major life decisions - career, partner, education, kids etc. There's less room for new experiences to alter that trajectory meaningfully.
One thing I've also realized through being lucky enough to enjoy some "semi-retirement" between work is having a healthy balance makes me appreciate both work and "leisure" more. It gets pretty boring to go to the beach every day, it turns out. I was itching to get back to building something by the end.
