I live this way in real life, with no preset conceptions of entitlement. It's very austere, but it also teaches self-reliance and appreciation. You aren't angered or disappointed when you don't get something you want from other people or circumstances; on the contrary, it's far easier to realize that wanting it does not entitle you to it, and thus you haven't been deprived of anything unfairly. It would be nifty if everyone adopted this style of thought for a day or two.when you learn that you're not entitled to anything in life, you become thankful. When you expect nothing, your happier when you get something, and a lot more thankful too.
