Love this! I am quite frustrated with inviting feedback and not getting it. It is like pulling teeth to get people to tell the truth. It starts to break down ones self-confidence on this never ending quest for self-awareness.
I can understand where you're coming from. My very limited knowledge can tell me, they may not want to put themselves into a situation of jeopardizing their relationship with you, their relationship as colleuge, member of social circle. Finally which might be as strong and if not stronger, what if they are wrong. What if, they give too much feedback, and it comes across as something you can't handle or don't take it the right way. As an accolade, most people when put into high positioned jobs who are not experienced - choose to play it safe, so they don't hurt themselves or others in a risky environment to impact their socio economic status. Lastly, I would consider were these the terms and conditions of the existing relationship? Some people just don't like, or have capacity to be this 'woke'.
A great presentation, would be improved withou the 45 second leading promo. (Unless your goal is to filter out the impatient people.) @16:00 "Ask the right people - Not everyone will tell us the truth. Don't ask unloving critics. Don't ask uncritical lovers. Ask people who you know have your best interest at heart, and who are willing to be honest when you ask."
