Make up your mind (but know when to change it)

One thing people look for in leaders is decisiveness Your inability to make a decision, or stick to one, can be highly frustrating to employees.
That doesn't mean you can't change your mind when necessary, though. The question is costs versus benefits. When you;re considering whether to shift course, try to measure the cost and rewards of changing against the costs or rewards of sticking to your present path.

If they're roughly equal, don't confuse your employees by switching things around. Consistency is generally better for everyone concerned.
