25. “I think building this culture is the key to
innovation. Creativity must flow from
everywhere. Whether you are a summer intern
or the CTO, any good idea must be able to seek
an objective test, preferably a test that exposes
the idea to real customers. Everyone must be
able to experiment, learn, and iterate.”
