Accidents on big mountains happen when people's ambitions cloud their good judgment. Good climbing is about climbing with heart and with instinct, not ambition and pride.
There is an old maxim which states that good judgment comes from experience, and experience comes from poor judgment. I think something similar can be said of government policy, to wit: Good policy comes from experience, and experience comes from poor policy.
Good judgment comes from experience and experience comes from bad judgment.
Foreign policy exactly suits Obama's strong points as a leader, which turn out not to be giving the masses a clear sense of direction and hope, but instead exercising good judgment on a case-by-case basis while thinking many steps ahead of the present moment.
When a man spends his time giving his wife criticism and advice instead of compliments, he forgets that it was not his good judgment, but his charming manners, that won her heart.
Since the team understands that the leader is de facto in charge, in that respect, a leader has nothing to prove. But in another respect, a leader has everything to prove: Every member of the team must develop the trust and confidence that their leader will exercise good judgment, remain calm, and make the right decisions when it matters most.
