Money or passion?

I am having this big dilemma right now. Money or passion? I love what I am doing now,having my student around me really lights up my day everyday. The cheerful greeting and the warm hugs are thing that you will not be able to receive in a office. I don't really intend to go back to a office base job either. Just that I have got this job offer that allows me to be with around with children and earn more than what I am doing now. The only cons are that I wil have to work on weekend.As for the cons, I may be able to get back my health as well as losing some weights.What Should I do??? The chance of me getting this job is like ninety nine percent!!! AH... Life really sucks in reality..
