Having answers is good.  Knowing how to use them is better.  Actually acting on them is best.  In essence, being able to do stuff is not as valuable as doing it.

Accomplishments require action.  Providing action instructions, in and of itself, does not necessarily get things done.  Getting results requires more than just identifying what is needed.

Buy-In

Even when you know what outcomes are expected, achieving them requires more than just insight.   Whether you are undertaking the action on your own, with or through others, to be successful everyone needs to buy-in (including you).

Without explicit approval or agreement to the course of action proposed (i.e., the answer) those involved will not feel ownership for the solution and so probably do not perform to their maximum potential.

Building acceptance and ownership to an approach requires more than being told or even knowing the right answer.  Everyone has got to believe it is the best way.

Doing it Right

Just acting on the right answer, that is getting stuff done is only part of the equation.  The approach needs to result in the defined goal.  That is a success means you achieved what you set out to achieve.

Knowing the right answer includes understanding clearly what the aim or purpose of the answer is.  To say you understand and know how to proceed without a clear vision of what success looks like probably translates to you not really knowing the answer.

The approach to achieving the goal, answering the question or problem is not right unless it works.
