There are notable exceptions, but in most cases a clear decision is better than hesitation or half-hearted execution. It's that old Yoda line about do or do not, there is no try.
That can be difficult to learn for those of us who are perfectionists. We would like to ponder a multitude of options while sipping a cool drink on the veranda. Unfortunately, there is no guarantee that doing so would improve the caliber of our thinking. There are times when you have to make a command decision, quickly, confidently and without all of the information, because you have the responsibility, the clock is ticking, and others are looking to you for direction. You decide and move on. If a mistake has been made, you take prompt corrective action, but you don't bemoan the unfairness of life and blame others.
This is an aspect of leadership that must be learned by doing or else you might not believe its wisdom. There are times when an well-executed poor plan can trump a poorly executed good one.
Much is made nowadays of servant-leadership and deservedly so. That is, however, very different from wimpy-leadership.
Be bold. Make a decision.
