There are a few key reasons people make sacrifices:
Someone is making me. “You may not go outside and play until you’ve cleaned your room.”
There’s something in it for me. “If you don’t eat ice cream for a month, I’ll give you a hundred dollars.”
I want to help someone else. “I’ll give you half my sandwich so you don’t have to be hungry.”
I believe in the cause. “I’ll stand outside in the cold in front of the grocery store and picket because I think it’s important for people to know the injustice of the system.”
Believing in a cause or vision doesn’t always result in radical behavior, yet it does often require sacrifice. But when you’re working toward something that you believe in, the sacrifice is always worth it.
