Depending on past success to determine future results is one of the biggest flaws a leader can make.
Because a person has flown airplanes for 30 years doesn’t mean he can’t crash. Just like a banker’s future is not insured from his past financial record.
Goliath had a great track record and lost to an inexperienced boy.
When people predict the future from their past victories they lose site of the preparation needed to meet future challenges. And the sad part is, it’s not usually realized until the stun of a defeat.
