Some traditionalist would say your home is your greatest wealth building asset. I would argue it is not. Others would say your income is your greatest wealth building asset. Thought there is a lot of truth to the statement, it is still not your greatest wealth building asset.

So, what is your greatest wealth building asset? Everyone is born with it. Few realize its importance until they lose most of it. The asset is so priceless it can’t be bought. Your most valuable wealth building asset is time.
