If you’re not attempting to be extraordinary, you’re an oxygen thief.
If you have the privilege of being paid by a company to create ideas (i.e. sit with your feet up on the desk, staring out the window, musing) then I believe you have an obligation to think big. To dream big.
To “take risks” with your thinking (at least at the early, conceptual stage) and to come up with ideas. Ideas that, maybe, no one has thought of before. Ideas that, again maybe, sound dumb.
