Beautiful post!
I've myself donated 40$ every month for 7 years to the cause I believe the most in: Providing cost-efficient education for girls in parts of the world where that is scarce. It is the one monthly cost I am determined to keep. If it means sacrificing that extra coffee pr day, or whatever else amounts to 40$ per month, I'll rather do that :)

Keep it up! Glad to see what you're doing!
