Yes, given "getting hit by a bus" is a probabilistic event that is independent of my working hours, I would rather make 2x for half as many years, all other things being equal. I'd also rather make 3x for a third as many years, and so on, if it were possible. Given time value of money and compounding interest, it's always better to front load your working time and make Nx for 1/N as much calendar time worked.

And for the controversial part: The above is why I think it's insane to, for example, take 1-2 years of not working, early in your 20s, to go see the world and "find yourself." Those 1-2 years, if spent earning, could mean retiring an extra 3-6 years earlier.

I agree with your conclusion, but I think there’s a fair argument to say that an extra week of leisure in your 20s is worth more than an extra week of leisure in your 50s or 60s. That is even more true if you’re working 48 weeks/year in your 20s and zero weeks in your 60s.

I think it's insane to, for example, work at an office early in your 20s, to put a couple grand in your 401(k). Those 1-2 years, if spent exploring, could mean finding a happier and more thoughtful way to progress through the latter 70% of your life.

I think this points out a difference in viewing everything in life as an efficiency problem focused on retirement age and overall wealth. Makes sense for a forum of engineers to see it this way I suppose.

Early on the money is probably the least important part. Momentum seems like a lot more important.

If you finish uni and take 1-2yrs off, that puts you wayyy behind someone who goes straight into a job. If you take 1-2yrs off your knowledge won't be fresh and you'll not really be a new grad anymore.

"getting hit for a bus" is a hyperbolic example meant to stand in for a catastrophic event. It really means you (or a family member like a parent, partner or child) has a major health event, for instance. Some things are random, some things tend to become more likely with age. Even just chronic pain or other health issues might make retirement less fun than travelling in your 20s (speaking as someone with chronic pain from surgical implants).

Besides health there's a lot of reasons why being certain about doing something now might be preferable to putting it off for 10+ years.
