Life's great mystery.
We as individuals have different wants and needs that's what makes us unique.
True. What is the difference between the needers and the non TT?
We all contribute one way or another but some people have a certain drive and ambition they are born with that drives them beyond the norm which is why we exceed in technology and great inventions.
But being human our weakness is our slow improvements on accepting ALL people for who they are.and be less prejudice.
