@kimmyfs My personal opinion,dont buy expensive stuff, buy stuff that makes you feel happy and worth it. Just because you want to spend does not mean you need to spend. I still remember during my days of getting salary, i used to spend on buying Roka (that 10 cent chocolate from mamak roti). My parents dont allow me to eat roka, so after each salary i buy a few just to enjoy the moment with it. The key is to enjoy the spending not spend to enjoy.
Another way to view this issue is the money not spent is not yours. You keep money in bank, of course you say its yours but then you die out of nowhere, now the money is not yours anymore. You keep also cannot use. Why not spend some to better some parts of your life.
Another Another way to view this is that you are single and unmarried with less commitment. Once the commitment comes your money goes. You buy a house, you'll see your money flying, you got married, you wont even see your money lol. So yeah before your money goes to somewhere else better it goes for yourself first
