Learn to Spot the Good Floor in the Wild.

By now your eyes have changed - you see middlemen and doorways everywhere you look. The final skill of this floor is turning that sight into judgement: walking into any industry, any town, any situation, and quickly reading where the real gap is, who owns the customer, where the money pools, and whether there's a doorway worth taking. It becomes second nature, a sense you carry for life.

Practise it constantly. Look at every business you encounter and ask where you'd stand to take the cut. Most people go their whole lives unable to see it. You're training a permanent instinct for spotting the good floor in the wild - and that instinct, more than any single deal, is what keeps you rich for the rest of your life.
