An inventor fails 999 times, and if he succeeds once, he's in.

Charles Kettering

Failure is an inescapable part of the journey to achieving something great — whether it’s a personal goal, an academic standard, or, for American engineer and inventor Charles Kettering, the next big patent. Known for such inventions as the electrical starting motor and leaded gasoline (among others), Kettering understood that a good innovator can — and should — fail as many times as necessary on the way to success.
