The problem with having the answer is it feels good.
Your brain loves it.
The rush of dopamine and adrenaline are terribly rewarding.
The problem with the answer feeling good is it becomes more than your contribution.
You become addicted to your ability to provide the answer.
Having the answer becomes an integral part of your identity, and not having it is devastating.
The real problem is you stopped having the answer.
You became the answer.
No one asked you to be the answer.
They asked for your insight in discovering an answer not yet known.
