Paying it forward a stitch at a time.
I recently asked this question of my testing group and also on my facebook page: "What are some things we can do with crocheting to benefit others?" It could be a "pay it forward" kind of thing or a charity. Here is a list of some of the things we came up with.

Donate blankets or lap throws to nursing home residents, lap throws for dementia units, lap afghans to veterans in hospitals.
Homeless people that you see asking for help - keep extra hats in the car ready to donate when needed.
Hats and scarves for the homeless veterans.
Blankets for the elderly at Christmas.

Police officers will often carry things like stuffed animals, hats, and blankets for when they have to remove children from their homes. Ask if they will accept donations.
Low income schools can often use donations like hats and scarves for the children. These would often come out of the teachers' pockets otherwise.
Food banks. Some collect hats, gloves, and scarves along with food donations to put in their Christmas baskets.
