My name is Gary. I’m 69 years old, and until one Tuesday afternoon, I believed I understood the people living under my roof.

I was wrong.

A week earlier, I’d quietly sold my three self-storage properties outside Abilene, Texas, for $19.8 million. After years of managing tenants, repairing gates, negotiating leases, and watching the land around me grow more valuable, I’d finally decided it was time to retire.
