Never, and I mean never, allow anyone else's ideas of who you can or can't become sully your dream or pollute your imagination. This is your territory, and a 'Keep Out' sign is a great thing to erect at all entrances to your imagination.

My method is different. I do not rush into actual work. When I get a new idea, I start at once building it up in my imagination, and make improvements and operate the device in my mind.
