Yes, only few of them really save their profit. most of them want to spend it buying all the things they want. For me, maybe thinking or more ways how to save it can help us.
And think broadly, after saving what are you going to do with your money? you are saving on a long term period but its value will decrease due to inflation. If something happens like what everyone is discussing now which is an economic crisis on 2019 then the money you save will have lower value. Yes, it is about the discipline and saving is connected to investing so while you are continuously saving your money, don't just let it go to the bank, look for some place where you can invest it like crypto's.
