Failure is...

...not an event, but a decisive response to an event.

Some might suggest the Wright brothers failed in their first attempts at flight.  They did not.  Without those initial attempts with somewhat negative outcomes, they never would have actually taken flight.  They were not the best supported and most funded attempt at flight, but maybe what they did have was the best perspective and understanding on what constitutes failure.

Failure is not dependent on an outcome to a particular situation.

Failure only becomes failure when the decision is made to not learn, grow and move forward from a seemingly negative outcome to a particular event or endeavor.

Failure is a choice not an event.

Don't be mislead.
