I .. uh .. did I tell you I can conjure a sandwich? Sandwiches are pretty nice. And takes away the helpless feeling we have when we can't directly affect the world in the way we would like to.
A sandwich will restore your energy, give you a sense of control (since you choose what your sandwich is made out of) and encourages you to make noise, sign petitions and spread the word about the dangers of mis/disinformation and why someone would want to spread such information.
Conjure your sandwich, then plant the seed of that truthmeter into the minds of people.
