People whoare too concerned with how well they are doing will be less successful andfeel less competent than those who focus on the task itself... Somepsychologists call it a conflict between egoorientation, or between extrinsicand intrinsic motivation...
A goodmanager doesn't try to eliminate conflict; he tries to keep it from wastingthe energies of his people. If you're the boss and your people fight youopenly when they think that you are wrong that's healthy.
If you are distressed by anything external, the pain isnot due to the thing itself but to your own estimate of it; and this you havethe power to revoke at any moment.
