You try a lot of things and you don't know what the hell you're doing. If you're actually inventing something you shouldn't know what you're doing.

Inspiration is really all around us. I pay attention to a lot of different fields. I stay up on current events. I go to community meetings to see what concerns the people in my neighborhood.

A lot is gained through experience, but experience teaches some and not others. Effectiveness and excellence, whether or not they were attained by simply having the knack or through the school of hard knocks, is really what you want to reward.

It's the building of things that makes you happy. You have to enjoy the process whether you succeed or fail.

You can change the format, make it easier for them to communicate or use photos instead of words but human necessities never change.

No successful company has had ever been the product of just one person.
