I've recently adopted the mindset that I will wait until things actually impact me before I will give them my finite attention.

This seems to get easier as I get older. Death is the only certainty in life and reflecting on that makes it easier to let go of things that are well beyond my control.

Maybe it helps you as well.

Additionally I highly recommend the book "Indistractable" by Nir Eyal. Best book on living a distraction free life.
