As I observed myself it looks like I never stop on planning to buy new things that I dont have yet.
You need to be satisfied for what you have not all you want you need to buy. Maybe help yourself make a decision for a good things so that you can be contented on what you have. And don't waste your money for the things that you don't need.
Satisfaction depends on yourself and on how you feel. You'll be contented in some things that you have is you appreciate the value of it. You just need to value your things and know thier worth just to make you satisfied. We don't need to think that the thing we have is not enough, just think that all we have bought or all we have now is a blessing. Even if you think its not enough, you just work for it and don't even think to throw away all the things you have. Even the simple things and small things are important and we have to appreciate the worth of it.
