Is What You Really Want A Need?

It's taken me a while to figure this out, and I've heard it
before. It really struck me the other day. Are the things you go
after and really want needs for you? Here's the difference. Being
in shape for me is a need. It's something I have desired my whole
life, but I turned into a need a long time ago. I cannot function
without doing it. So are your goals wants or needs? Can you not
function in a day if you don't make any movement towards them?
