I am an idea person. I also am someone who constantly thinks of new solutions to old problems. The greatest obstacle I face is the "no" people, who seem to exist in numbers far exceeding the "let's try" or "here's another idea" people. I find it exhausting to be in groups (a requirement at any university) and to constantly hear negative responses or silence. I finally gave up, refuse to work in a university and am now running my own business, where the boss (me) demands creativity and new ideas. Nirvana.
