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?
I'm actually partly like you, though i don't spend all my bitcoins i earn every month but i spend a part of it on myself and keep another part, though i feel i'm not too good at managing money but i actually do some saving which can be considered a good part of managing money i guess.
