Thank you for this, I think it's now more about trying to become fulfilled in whatever position you are in life and trying to make the best out of our lives.

Although, as you said, there isn't a right way to live, but I personally think that we should strive for improving what we can, with the little power over the world we are given and to avoid hurting and making other people's lives worse.

I already regret not doing the "meaningless" things I thought were a waste of time, like spending more time with my now deceased dog. I took for granted that he was alive, and never really spent nearly as much time as I wish I did, thinking that an hour of work was more important.

The thing is, I don't think spending time with loved ones (your dog for example) is meaningless, infact I think it's very meaningful.

Well said!

I'd like to add that even scrolling social media like Reddit, Facebook, Lemmy etc can be meaningful. I find it's like walking around town looking at what other people are doing. Listening in on someone ranting from their soap box, participating in some open air discussion, looking at cute cats in the park and learning something from a mechanic talking through a problem with someone standing beside a broken down car. It's also a social experience even though it can't be your only social exposure it still provides something.

It really is about variation and moderation. It wouldn't be meaningful, in my opinion, to spend your life on a rotation of the gym, cooking healthy, reading about those topics, working hard at some nameless corp and sleeping properly. But if you don't normally go to the gym it's suddenly meaningful to go. Life is about experiences and about challenging ourselves to find out who to be and how to be the subjective "best" version of ourselves, and that quest has no truly meaningless activities, all roads lead to the end of life and while we might regret some activities that regret in and off itself is a lesson that we took with us.

Since reading some other comments, I don't know what is meaningless anymore, I now think that you could find meaning in everything if you looked.

I think rephrasing the original would do better, it should probably be about living a fulfilling life without harming others and not ignoring good opportunities because you think you should wait until the perfect time that'll never come.

However this ignores unavoidable pain that we all get in some way or another, in your case mental health, so I'm still not sure what would be a good way to live, as we aren't always in a decent enough position to take up the kind of opportunities I said earlier.
