MB you hit the nail on the head. We really don’t have a good understanding of sacrifice. Not having a latte in the morning is not a sacrifice it is an inconvenience. Even many of the examples you listed were not really sacrifices, they were a means to an end or goal. We have gotten so accustomed to luxuries and consider not having them a sacrifice. A real sacrifice as you stated costs with no return on investment. The father knew he would likely die but to him his sons life was worth it.
