Don’t just listen to cable news and partisan radio shows, read studies and learn the statistics/background so you actually understand what they mean. Look up primary sources to get perspectives from younger people who may face very different circumstances than you did at their age.
You have a whole life of experience that can help and hinder; take the time to understand the changing world instead of clinging to the past so you don’t just make things worse.
From my own experience it’s disappointing to see older people ignore or stall on a variety of social issues that no longer affect them because they’re set. Even worse, some ignore or pooh-pooh serious long-term problems just because they’ll be dead when the ill-effects kick in.
I’m not sure what to blame for this selfishness and myopia, but it’s important to remember that “uninformed” is not just an adjective that applies to the young.
