What would you sacrifice for world peace?

I’m in a contemplative mood

For me… I really don’t know. I can think of some really huge things but I don’t know if I am a big enough person to give them up. The biggest thing I can think of was to never see my family again…(Not including my son. I wouldn’t give him up for anything) But then I thought about how miserable I would be. I don’t know if I could do it. So I’ll say I’d give up my education for right now. :) Maybe after spending some time with some monks or something I will change my mind.
