Yes, that is right and you know it. At least in most cases and in most everyday matters, necessity brings us innovation and invention. It would be best if we could invent without necessity but it seems that the way humans are structured we best invent under the pressure of necessity. And God only knows if this can be changed.Is this good or bad? I don't know. All I know is that life is great and we need to keep on inventing new ways to have fun. So live on today too!
