personally i never really understood this point of view. whether it would matter what i do in my life 500 years from now or not, i'll be dead anyway. i think it's a low self esteem issue more than anything. people that are mentally healthy find meaning in day to day activities and that's plenty enough for them to enjoy life.
I know I'm not mentally healthy! All I think about is the fact that I don't matter, nothing I do matters and that I feel my only purpose is to do things for other people to justify things and eliminate risk. That's just me. Whether it's healthy or not is obvious, it's not. More than anything as a child I wanted to grow up to make sure my work and life had meaning. I've learned that the only thing my employers care about is that "the proper iso standards have been procured and meet the standards for moisture vapor transmission" which means I've gone to college for 10 plus years, gotten advanced degrees and live a life solely so that documents for regulators have boxes checked that no one will ever read or use unless there is an audit that someone does and all that will cause is more paperwork. My whole life means just some crap on paper to prove papers match up. There is no creativity, no joy, just hundreds of people wishing they didn't have to do what they do or trying to find meaning in moving paperwork around. Everywhere I have worked in engineering this is what we do. We don't create and build. We spend thousands of hours testing and covering our asses. And when I die they will have to convince some other dufus to keep the same stuff going because it is important.
I once tried the following for a company I consult with: "I said, I'll work for you on projects but I don't want to be paid. I'll work for free. My only specific point is that I want to be able to refuse with absolute perogative to not do things I would rather not do. I'll advise on manufacturing, I'll help with development, I'll answer questions, and I'll consult with the research teams. On quality assurance and regulatory I will choose not to work on those items and will not respond". The president of the company was explosively livid. He couldn't have his board take that risk. I don't see it as a risk at all. I think he knew that if I had no contract and was refusing payment they couldn't have any leverage to make me do that shit. They still come back over and over again trying to get me to take money.
I bet that a local sandwich shop needing employees would not take an employee who said "il work for free but only if I get to choose my own schedule and not do demeaning tasks" even if that was the best employee in the world. Our lives are completely part of crap that is trying to get crap done to justify and ensure that crap gets transferred to other people without risk.
I truly hate my life and hate who I am and I don't want to reframe myself. I have made enought money for a reasonable retirement, have no debt, have my health and my kids and I find that it's all been completely meaningless crap that has benefitted no one except people who push around paper and that forget about 500 years, it will have zero important in 5 years. No one but regulatory agencies will benefit. It's true that someone can explain why something is important in the following terms as though making you change your password is important "in order to protect our customers and our company we require that you change your password every 90 days..." But is it really that important? Does it really help protect the company or the customers or is it just covering the butt of the IT people? Can you actually state that "making you change your password into something you can't remember every 90 days" is what truly helps the company and customers? Is it actually valuable? Or do the people who want it done for covering risk convince you it's valuable so that they don't have to deal with you trying to search for meaning and value in your life when it's all just crap.
I believe all of the easy problems have been solved, all of the important projects have been completed, all of the good ideas have been had and all that's left is just justifying risk reduction and trying to tell yourself to "find joy in the little things"
If that's not what you want, you want to do things that matter and you want to have significant impact and help with what you do, there are no avenues for you to do it. Unless you reframe to make life have meaning on terms through rose colored glasses, life has no meaning.
