Worth double-checking charitable giving to make sure it actually helps the cause you care about
Surprising amount of charity is of this kind.
My ex, Tess, and I used to give to Koala Rescue. Years later, I found that they just sort of assign you a random ~bear that lives outdoors. Hundreds of people have the same one. Your money doesn't buy it food (they only eat one thing), but rather goes to support various green causes.
Etc.
