If you have a family ,it will teach you how to save money for your future. But if youre single and dont have any plans for the future you will not know what is the meaning of saving if your totally have nothing.
Best way to save money is to invest in something later that you are worth it. If you have money in cash easy for you to spend it on some unimportant things. I also think it's a very good thing to invest money in real estate, rent and real estate for several years, then sell it again and be positive.
but real estate need lots of money to invest. you can't even buy a peace of land with thousands of dollars. but if you have lots of money then probably yes. real estate is a way to safe your money. because paper money won't be safe for long. buying real state will safe your wealth for long time.
and buying gold is also a good way I guess.
