Just logged my 10,000th hour in the cab and it hit me different

I was finishing up a job moving steel beams for a new warehouse in Tacoma, and my logbook ticked over to 10,000 hours. I always thought that number was just a thing you hear about, like the '10,000 hour rule' for being an expert. But sitting there, it wasn't about being an expert. It was about all the mornings I got up at 4 AM for a pour, the times I sat through a storm delay for three hours, and the muscle memory of a thousand lifts. I remembered my first day on a small mobile crane, shaking so bad I could barely line up the hook. Now I can feel the wind shift through the seat. Has anyone else hit a big hour mark and had it make you look back on the grind?
