Further validation will not help.
If you are stuck on something, affirmation from others is not going to move you forward.
Seek a different perspective. Someone in a different industry, role or world view. Someone with a different perspective, a way of thinking, a frame of reference unlike yours.
They may not directly give you the answers you seek but I wager they will get you thinking if you are open to listening.
It is not what you already know that will help you grow, rather what you are yet to discover or consider.
