Failure isn’t final. It’s necessary. It’s the fuel that allows you to advance, to succeed. (Tim Kennedy, military author)
Kennedy was a success in many arenas, as a soldier, professional fighter, and in heroic rescue attempts in the Middle East. In Stars and Scars he recounts the many times he failed. Each time provided an opportunity to change arenas, start over, and work toward worthy goals. The thought that failure is necessary is a mind-changer. Building on what failure teaches is a key to success.
Plans go wrong for lack of advice; many advisers bring success (Proverbs 15:22).
