if I may be honest I always spend all my salary to buy a certain item I like, yeah I'm very hard to control my desire to buy something, there is the suggestion that I was not too extravagant?
its not good to spend all of your salary because i think you need to saving if in case you have emergency situation. and beside that, i think you need to control your desire to buy something you like. better to buy important item and make the rest in your account in bank so you can trying to save your money for your future.
