The average citizen (not organizing protests and keeping away from fruitless online outrage) can probably catch up with all relevant political news in 1-2 hours/month of concentrated effort.

I've started doing just that and it has had great impact on my mental health. I don't feel any less prepared to make an impact when the time comes (elections, sporadic talks with friends and family).

Should I be more engaged? Surely. But I just look at all of it and think it's a necessary evil and I'm happy other people feel more inclined to participate heavily. I just don't have the mental skills to keep up and be sane.
