Collboll - Mitt liv i Gambia

Why is it that we always wish for the things we dont have? That we constantly looking for new thing, we want new cloths, new hairstyles, new boobs and new life's. Why can't we be happy about the things we have and be grateful that our life's are wonderful without all of this things? Why are humans so hard to please? Even if I had all the money in the world I'm sure I still would be searching for new things. I just think its stupid to wish for the things u don't have when u instead can be grateful for the life u already have..
