The “Die with Zero” book may go a bit overboard but I think the general message is a good one - do not OVER sacrifice today (and your youth) for a wealthy future you can’t enjoy.
The Bogleheads forum is full of “I scrimped and saved and now have millions but I can’t even bring myself to buy a used Toyota.”
It’s such an old problem it’s mentioned in Ecclesiastes 2:21-23!
Another way to look at it is you have time, effort, and savings; you need to balance them all because time will run out. A local college kid can do things that Buffett will never be able to do, because he has youth and years, and no billions can buy those.
