Tip that will work forever, even when the ones you replace your old idols with get replaced: Don't have any idols.

Listen to the words, don't follow "personalities", don't listen to specific individuals just because of their status. Not a single time have I been disappointed by an idol, because I've made the conscious choice of not having following any. Bunch of smart people say smart stuff all the time, until they don't. I read everything as if I don't know the author, I think more people should do this and less celebrity worship would make the entire ecosystem better. We need less of it, not more.
