If you're earning it ... how does it not belong to you? you're working for it.
Anyway here's what I would do with it in order:
1. Pay off bills (credit, cars, extra on house payment)
2. College fund for kids
3. Retirement account
4. Savings account in case of income loss for some reason.
5. Other Charities.
But that's just me :) Lots of options for charities, but I'd start with local charities.
