As I observed myself it looks like I never stop on planning to buy new things that I dont have yet.
It still depends on how you manage you time and budgeting. It also depebds on how you discipline yourself in controlling the things that is not necessary for your daily living. The better thing to do is to be satisfied for what you have and be contented in it. Appreciate every little things you have and focus on spending what you have on things that is more important for you.
