If you are upset by the way things are in the world and you want to change them but you don’t know how or you are afraid of what it may take, look for inspiration. Find others who are engaged despite what they may lose, find others who act despite what they don’t have, find others who know how to do it because they’ve done it before.
Try to meet and learn from these people in person.
If the state of the world troubles you, the only thing that will change it is joining together with other people. Doing that (even though it might seem scary) can produce joy and some inspiration in and of itself.
There are always people resisting, joined together in struggle, and it’s amazing how inspiring their actions are once you find them.
