Ways to help promote self improvement for a better world?

[Fireball]

I'm posting this in the Arts forum because sometimes I think of it as a performance art, and I don't see any better fit for it in any other forum. It won't hurt my feelings if it gets moved to some other forum.

Sometimes people try to improve themselves, to help improve the world for everyone in the world, or at least for the people around them. For example they might try to learn to be more kind or more patient, or to be a better listener or a better friend. Does anyone have any ideas about how it might happen that more people would do more of that, and how any of us might help it happen?

For me, it starts with practicing that myself, working to improve my own character, my conduct, and the way I live my life, in ways that might help make the world better for all people everywhere. Trying to learn to be more environment-friendly for example. Then to try to learn to encourage and support other people who are trying to improve themselves for the benefit of others. Then to learn to talk about it more, with more people.

I asked this in another forum, and got some good ideas. I decided to see if anyone here has any other ideas. Some ideas I've seen or thought of so far:
1. Practice it myself and be an example.
2. Become better friends with more people.
2. Encourage and support other people who are doing it.
3. Learn to talk about it more, with more people.

Any other ideas?

The biggest challenge for me now might be #2.

(later) Another reason for discussing it here could be because one of the best ways of promoting this might be through the arts.

Given that you are in China (?), #2 could be a challenge. It's a known thing that as men age, their circle of friends diminishes. I know that it is true for me, but I'm opening up to find more people. I spent so much of my time working and supporting my family that I made little personal times for friendships. Spending a lot of time commuting meant that I missed a lot of what my spawn did in school- track meets, swim meets, music recitals, etc. Whenever I talked with younger people where I used to work, when they asked about moving to an area with a lower cost of living, I always counseled them to stay close to work if they could possibly afford it. As the mortgage becomes less dear in cost for them, I hope that they will appreciate that advice. I'm retired, now, so have lost contact with a lot of them.
