Being innovative to me means for you to come up with an idea that is like nothing that already exists. It does not have to be an invention. It can be an idea that will help society function better. Several times throughout history people that have been innovative have been called crazy.
They have to stand out from the crowd and fight for their invention or idea. Some people that I think are innovative are the Wright Brothers, because they made something so out of their time. No one thought it would be possible to fly. They did it though, and that is what matters.
