Cautionary tale: Options - don't overdo your luck

I have been swing trading last 3 years and modestly have made in between $2K-$3K in profit every month (no day trades - I have a separate acct for swing trading and keep it a no round trip on same day acct) Nearly all my wins had been below $500 with no more than $5K on the line. Win ratio in between 75-80% because I am ultra careful and sometimes even got away with less than $20 profit on 1 contract. Was till NVDA. I made a $300 ITM call with 10 contracts 2 weeks before earning to be held 1 week after earnings (Friday expiry a week later). Made nearly $80K - very comparable to my entire 3 years win. Got greedy. Increased contracts and played what was pretty risky IMO calls. But market kept going up and made $17K approx more in 2 months after that. On Monday despite my inner voice telling me not to do so , played 15 NFLX calls at $470. Down $55K in a flash. I think it's going down more - so took my losses. Still up for the year, but wondering how I could be so blinded by greed against my better judgement.
