if you make money just to eat, I think it's a big mistake in life, don't blame your little money, but build yourself up even more to be able to earn more money so you can meet your needs, desires and invest for the future.
I think some people only make money to eat because of limitations in making money and that is not a big mistake in life because it is our way of survival. Even though they are like that, they still believe that one day their lives can change and even though they can't enjoy it, they hope their children will.
