It requires relatively no effort just discipline for anyone to save money and live within their means. yet, most don’t most always have an excuse. Within the design and engineering department that I worked in more than half of the people did not save always had an excuse even before they were married and had kids.

Just setting aside 25% over time adds up to a sizable amount.

25% is a huge amount. Yes, it adds up. Over time, you don't get me wrong. But you need to ask, should you do that much?

Everyone will die, despite great medical advances over the past century. Someone who lives past 5 and doesn't die in childbirth, or an accident - only got a couple years of life expectancy. You should be thinking of saving money as this is something we're going to spend in the future. The goal is not to get the most money on paper. The goal is to... Well, you figure out your own goals. I don't know the right answer for you, but to try and enjoy life with the money you make.

Most people don't have that discipline. If you asked the average person to "just" save 25% of their earnings, they'd look at you like you had two heads.
