I'm not comfortable with the thought of not being able to buy the things that I want to have, eat the food that I'm craving for and travel to new places that I want to visit in the future. So this early, I don't use everything that I earn. I try to put most of it in savings and investments. I don't buy gold coins but I do buy shares of stocks. I also have some savings account.
I teach my son to save for his future also. He has savings accounts from different banks and he has investments in equities as well. And he's only 10 years old. It's never too early to plan for your future. The best time to start is today.
