You can't be certain of that, though. If you had (for example) pursued work and money more ambitiously in your 20s, maybe those relationships you value now would never have formed in the first place. Maybe then-existing relationships would have suffered to the point of estrangement.

I'm lucky: I worked very hard and did decently well in the startup lottery, but I still left myself enough time to forge valuable relationships. I've witnessed people who chase higher and higher salaries but aren't that lucky, and end up using the years of their life where their mind and body are at their peak of their ability for work instead of play, and regret it.

I'm in my 40s now, and see some younger friends and acquaintances doing things like taking multi-month world trips, diving head-first into new hobbies/skills that take hundreds/thousands of hours to get good at, and I wish I'd done things like that in my 20s and 30s. In part because my responsibilities today make it difficult to do now, but also because I just don't want to do some of those things anymore, because they sound kinda exhausting at my age. But I still wish I had those experiences in my past to look back fondly upon.

I guess what I'm saying is that nothing is certain, and we can't reliably look back and say "if I'd done X 15 years ago, today I'd be able to do Y". Life just doesn't work that way. I think we should do what makes us happy whenever we have the ability to. Sure, look hard for and always be open to opportunities to take on work that could make a big change in your financial life. But be careful with those sorts of choices, because there's always opportunity cost.
