Two years of active day trading. The smartest way of gambling, the cheapest MBA in risk, and the most useful lesson I've ever paid for.
Two years of active day trading on real capital. Not a paper account, not a course, not someone else's strategy. I built my own watchlists, my own risk rules, my own playbook, and I broke them, fixed them, and broke them again until I learned how the market punishes inconsistency.
I don't day trade anymore. The strategies I still use are longer-horizon and quieter. But the muscles I built then are the same ones I use when I'm running multiple products at once: triage fast, size your risk, take the loss, move on.
You can't fake this skill set with a course. You earn it by being wrong, often, with skin in the game. I've paid that tuition.
