I have learned (and still learning) to pace my self emotionally. In our fast-paced, information-saturated, constant communication culture, there is a magnet that keeps pulling us to depression, negativity, and unhealthy thinking. This pull is not just cultural issues, but the ability to discover so many things that impact family and friends.
So, as you keep caring for your world, care for yourself. Find out the things that fill your positive emotional reservoir, and lean into those gifts.
