I feel like most of us still have a lot to learn, probably until they hit the ages of 40+ but eventually that has diminishing returns when you get older...

It is nice to read the variety in this post, and a few things really caught my attention.
When you're young and inexperienced about life in general, you tend to deal with things very differently. Somehow, when you get a little older, you can look back and realise that you could have dealt with certain situations in a much better way.
One example for me was when I was at the peak of my career and in a position of authority. It was very easy to become a little arrogant, especially when I was doing really well, knew a few things, and felt like I had control. It's easy to become proud of yourself when you feel like you can turn a few things around with your fingertips.
Before you know it, you can start identifying yourself too much with your job, profession or position. But those things are not forever. If you build your whole identity around them and then they disappear, you can suddenly find yourself lost because you have identified so strongly with what you did rather than with who you are.
I think this is something many people miss. Knowing yourself is a powerful tool, especially when it comes to coping with changes and setbacks.
Experience also helps you understand other people better because you've been through certain situations yourself. Eventually, you learn to recognize and understand different kinds of behaviour and become better at dealing with both situations and people.
As we get older, it is said that we can become slower at learning new things, but all the accumulated knowledge and experience can also make us better at applying what we learn to what we do.

And I like Hive, which is one of the reasons I'm still sticking around. It's not just that you can get rewarded here but you can also contribute in a way that benefits the rest of the community. That part is important to me. You're not only here to take something out of the ecosystem for yourself, you can also put something back in and help other people benefit from it. Oops, I got a bit carried away and made this longer than I intended, haha. Sorry!
Have a lovely day! 😄
