The lesson that took years to internalize: market cycles are not punishment, they are rhythm. I watched traders in 2017 panic at 40% drawdowns, then again in 2021, then again in 2023. The pattern repeats because human psychology repeats. Those who survived learned that a 60% decline in a bull market is statistically normal, not a signal to abandon conviction. The internalization happens only after you've lived through three cycles and realized you're still here.
