I’m in possession of a curious nature, and read, watch and listen to all manner of ideas and things. EG I subscribe to WaPo, the WSJ, The Guardian, Le Monde, Financial Times, Russian TV, The NY Times, Reason, etc. It is how you learn.
I am 70 years old. I am under few illusions about the world and the range of people in it. I will not get to see the changes in behaviors that mankind must make if it is to survive. I do my best to conform to some of those needed behaviors. And I initiated some changes, eg fighting and winning a case at SCOTUS (thank you, Nino Scalia) that changed constitutional law. The rest is for the next generation to do.
