I am a Introvert, which means that I get most of my energy from myself. I dont need other people to pump me up or try and get me to do something. I am either going to do it or not.
J preference; for closure and completion, I am generally a "doer" as well as dreamers.
My product would be a Solar Panel because i get all my energy from myself, even though the solar panel gets the energy from an outside force ( the sun), Im thinking about it in a different way.
