I'm a Dead Man Walking?

I've started to get more aggressive in my current trading with SPX options and it's happened…I've been told I'm a dead man walking! I'm told it's only a matter of time before the market owns me! Here's the thing though, this person was right and I "got owned" in a single losing trade that erased, literally, nine days worth of gains! Yet, I'm still nicely green on the month! Huh??? This opens up a great discussion on how trading strategies can work and how you can wisely go about developing a strategy to suit your needs. I'm not the greatest trader on the planet; however, I have been trading for almost two decades so I'm done enough dumb things that I now know to avoid. Let me walk you through this accusation of being a dead man walking and how it's accurate to an extent, but overall, not really.
