Do we have expectations that can be met by mere men? When we create jobs or tasks, is it possible for the average person to complete the task?
We must take care not to defeat our peers, subordinates, children, or spouse with tasks or expectations that no man can meet.
However, you need to be the one who can look humbly and wisely into what the person has accomplished and determine, based upon that, what is likely they could achieve in the future. We’re generally lousy auditors of ourselves.
While we want tasks and expectations to be reasonable, they must not be without a challenge. The challenge will bring out whatever strength your subject has–if you dare to press him.
It’s all a balancing act. There is a fire in the belly of young people, but if it’s is not well-managed, it will lead to burn-out by early middle age.
