Between my animals and plants I never run out of things to do. If I'm not actively taking care of them or some other thing I have to do, I'm daydreaming, researching, planning projects having to do with them. Buy a $2 pothos plant. You will spend the rest of your life figuring out creative things to do to with it while keeping it and its clones from taking over your entire house. You will try to make new friends just to have people to give cuttings to.
