Take as much as you need

It could be "love", or it could be "hugs".
It could also be "something interesting", and you could write at the back a food-for-thought quote, an awesome website, or a place in town you love.
It could be, as well: "The Revolution" take as much as you need. And on the back you could encourage people to do little actions to crack capitalism, as John Holloway theorizes about.
As always, it could be anything you want it to be.
