There Is No Answer, and That's the Point
Horowitz ends without a formula, on purpose. There is no answer to The Struggle. No framework dissolves it, no technique makes it painless. The techniques are handholds, not exits. Sometimes it just hurts until it doesn't.
What he offers instead is the reframe: The Struggle is where character is forged. It's the crucible that separates the CEOs who become great from the ones who break, and going through it is the price of the job, not a sign you're doing the job wrong.
So the closing note is simple encouragement from someone who lived it, nearly went bankrupt, and came out the other side. If you're in it right now: keep going. That's the whole instruction.
Key idea
There's no trick that ends The Struggle. The techniques help you survive it, and surviving it is what forges great CEOs. Keep going.
