Finish a big project at work before the deadline? "Is this meaning?" Obviously no. The big project won't impact the mega-conglomerate's bottom line. And if it did, what's it mean to increase the revenue of your employer by 0.001% YoY? For you, personally, that is. Etc.
Just got married? "Is this meaning?" Again, no. Anyone can get married. Most people do get married. It's incredibly common. You're not special for getting married, yet people spend lavishly on weddings to force some amount of "meaning" on the occasion. The day before your wedding isn't different than the day after. I've been to a dozen weddings and can really only recall the details of maybe two of those.
I've not seen a more miserable group of people than /r/fatFIRE on reddit. They have insane wealth, go to retire, and find their life hollow. The mistake is thinking there is some reward is at the end of the journey. I have $30 million dollars, I've retired, now what? You either fill that hole with giant amounts of crap (new Lambo, fancy house, huge TV) or "experiences" (which really translates into traveling to places where poor people are your temporary servants because of the gross power imbalance wealth has granted you). Or, more work. The real secret to retirement is... maybe don't?
Hayao Miyazaki is still working, and certainly doesn't need to. He also doesn't believe that personal happiness should be a goal (it's a very Western point-of-view), and considers filmmaking to be suffering[1]. And I suppose that's the real reward for having kids. The meaning is the work and the pain. You'll change a child's diaper thousands of times. But you'll also get to see them smile and laugh.
It seems you’re saying there’s no meaning to life if I understand that text right.
I don’t know about you - but am a regular reader on fatfire fwiw and I do find my life immensely meaningful. I like finding goals, working towards them and possibly achieving them even (sometimes) or refocusing again. I look at the human experience as the meaning. Money definitely allows for varied experiences while I can pawn away the grunt work of living. Take it for what you will!
If you look for external sources of meaning (big house, cars) are really just looking for validation. You want others to think of you a certain way.
But if you genuinely enjoy cars, and driving/working on them puts you in a flow state, that’s great.
Most people suffer a lack of engagement at work and should retire to work on what they actually enjoy. If Miyazaki enjoys his art (he enjoys it in the average, looking back, glad he did it after all, like exercise) then of course he should continue. A rich, bored retiree is miserable because they realized they were chasing external validation, which is truly hollow, and can now begin the process of doing what is internally meaningful to them.
Asking whether something is meaningful, in your heart of hearts, lets you sidestep decades of chasing the wrong goal.
