Yeah, first of all, let me just empathise with you. I know it's not comfortable. I make all my audience say with me, "Let's all say the four scary words, 'I do not know'", and we say it together. And I say, "And I know you were brought up as leaders not to say those words. But what's happening now is, if you pretend you know and you don't, you could be leading your team down a very dangerous path. You have to acknowledge what you don't know as an opportunity to learn, because the first step of learning is to say, 'I don't know', because if you know, you're not learning".

The wisdom of what a person says is in direct proportion to his progress in learning the holy scriptures — and I am not speaking of intensive reading or memorization, but real understanding and careful investigation of their meaning. Some people read them but neglect them; by their reading they profit in knowledge, by their neglect they forfeit understanding.

The Sage

A person of wisdom should be truthful, without arrogance, without deceit, not slanderous and
not hateful. The wise person should go beyond the evil of greed and miserliness.
To have your mind set on calmness, you must take power over sleepiness, drowsiness and
lethargy. There is no place for laziness and no recourse to pride.
Do not be led into lying, do not be attached to forms. You must see through all pride and fare
along without violence.
Do not get excited by what is old, do not be contented with what is new. Do not grieve for
what is lost or be controlled by desire.

Wisdom is something which will come out of your mindfulness. So the point is to be ready for observing things, and to be ready for thinking. This is called emptiness of your mind.
