I really do need a break

How do you make everyone including your friends and families understand that what you are doing is for the sake of this country and the future generation and yet stop short from sounding too corny and idealistic especially to the cynics and to those who would not be able to understand it? Yesterday both my eldest son and my youngest daughter asked me if I am taking some time off from work and would take them abroad. I told them "no sayang, babah has to work" My son cheekily suggested that I should just quit my job.  They started to make comparison that in my previous job, I was able to take time off and bring them abroad like to Singapore or Malaysia even for a short break during the school season.  It is very difficult to tell them that now things are a little bit different. I have more responsibilities and I am more accountable to a lot more people. Even my mum started to make comparison. She came to my house yesterday and began to "sindir" me by saying that my amit (her older sister) has no problem in seeing her children as they would usually spend every weekend together at her home. I just wanted to make her understand that now because of the bigger responsibility, I have to be a public servant first in many occasions and being my wife's husband, my kids' dad and my mum's son would have to fight for second place.  For the last few days, I virtually had no understanding of what day and date it was as I actually had to work on friday and sunday, night and day.  For that part of me as a husband, dad and son, yes I do need a break but I cannot simply abdicate my responsibility as a servant to the public at least not when the public is expecting to see results. I have a mission and I have a mandate. I just wished everyone around me understand me that.
