If money cannot buy happiness, can you ever be truly happy with no money?

If money cannot buy happiness, can you ever be truly happy with no money?

I always hear people saying money cannot buy happiness, but is it really possible to be happy without money? Almost everything in this world requires money to do, unless you're being one of "those" and living in a forest growing/hunting your own food. I'm not just referring happiness to buying houses or living luxurious, but also to simple short term happiness such as buying an ice cream cone or getting clothes.
