I do agree that a lot of people are more concerned about being seen/heard instead of doing something good. But I do think that in history, a lot of good was done and invented because people wanted to be remembered. We just need to redirect the energy from trying to be popular, into making/doing something that will make people remember.
You have got it. This is the thing, isn't it? Doing something meaningful in life, something memorable, should be something that improves the lives of others.
