It seems quite a bit of your writings are being murdered.
But, on point: "Meaningful is a relative concept, and I sincerely hope people in this thread don’t fall in a trap of comparing what they’re doing so what others are or are not doing."
I almost did. I've been feeling like I need to keep on grinding and moving on to more and more lustrous work, for some reason. Perhaps its to feel like I'm not "falling behind" in the "pack?" Perhaps I simply have too much time to ruminate, and not enough other tasks and hobbies to "round out" my life. Nonetheless, I've caught myself. Thank you.
With age, I'm adopting your point of view: work is simply to live. If it's work you're interested in and has tolerable-to-good coworkers, all the better. If not, well that leaves me to find "meaning" elsewhere/some other source of the "everything is on track" emotion.
I think we're all insignificant in the grand scheme of things. Our work simply makes no difference in the world, and serves only to keep the commerce machine churning -- till we die. In a previous time this notion would've been harrowing, but now it has no weight. That's simply life.
A good friend, through years of soul-searching, has taken to "altruism" via local non-profits and just being a good person to those within his personal sphere. Something about it rings of depth and goodness, in comparison to the usual and shallow bombast that rings empty from all those spouting about "revolutionizing," "changing the status quo," and "making the world a better place."
I feel the latter is simply done for the self, while the former is truly a self-sacrificing act. Perhaps being a decent human being towards those around you is the most meaningful thing you can ever do. It certainly doesn't have the manic high of "I'm doing something important, something impactful, and something BIG!" It's a mellow and tranquil feeling -- one too weak to get high off of. So why does he go through with it? I think its because he's purposefully developed a moral fiber. It's not grand, nor does it excite, but it's coming to be one of the only aspects I truly respect in others.
Achievement, accomplishment, importance, prestige, and so on, is all just grift in the end. A massaging of reality to make others perceive you in a different light so your ego/self-worth/emotional need is satisfied. Whereas a detached decency towards one's fellow man is not so.
