Off course not.But wanting something that is not appropriate for us is definitely wrong.
It all depends on what you want. "Is it necessary?" "Why do I want this?" "Is this reasonable?" are questions that only your conscience can honestly answer. In my life, I have learned to find happiness in things that are mostly immaterial (material things may bring temporary satisfaction (or not), but definitely not lasting happiness). I like to go shopping every now and then. Moderation and a little bit of reflection seem to be good guidelines when it comes to "wanting more."
No, not if you're prepared to give more in return ...... when the time's right
It is a good sign and desirable to want more.
Wanting more of a happy life is not wrong if you pass the happyness around.
