needs: are the basic things we need.. like food, clothing, transportation. wants: gadgets, expensive cellphones, foods in a expensive resto, buying very huge house, etc. There is a principle that I learned from the book 'Wealth' it is said there that we should follow the Pareto principle or 80/20 principle. From your income, the 80% will be used to satisfy our needs and 20% will be our savings for our retirement. Why did I say this? Because I am tired of buying things that I don't need, I have many stuffs in my room. I felt like, I wasted my money through those stuffs. Instead of putting my money in a bank for an investment. I'll update you guys about that book, on how to save our money right!
If you don't want to buy things that you don't need- minimize the use of your credit card or just stop using it if you can!
