First year trading full time. Up 83% and scared about next year.

Started the year with c. $222k. Woke up to $409k this morning. Up 83% while S&P's done 12% over the same stretch which I understand is rare. Want to be honest about where that came from, because the number is misleading. Roughly $84k is premium from selling options. That part I understand and can more or less repeat. $151k if it is from one position, MU. I was right, but not for any clever reason. I bought before Q1 earnings (around $430) as I had a strong feeling they would crush it. It tanked, I panicked and bought more all the way down to low $300s. I made some horrendous decisions selling covered calls below my cost basis to try recoup and thats when it started to moon. Luckily, I had an okay strategy so that I could close and roll all the way up until I finally exited a few months ago near $1050. I used a ton of margin too which gave me many rough nights. This is my first year doing it full time. April nearly ended it. I was down to $147k at the low and I'd started working out what I'd say when I went back to a job. That's not me being dramatic, that was the actual plan. So now I'm up 82% and feel two things at once. Proud, I stuck to the process, didn't blow up, the premium engine actually works on its own. And a sense of dread that I've just set a benchmark I'll never touch again, and every month from January is going to feel like failing. What's a sane target for year two? I keep landing on something like 40% and I know that's just the 82% talking. Do you set a return target at all, or an income target, or drawdown limits, or something else? How do you stop one lucky year becoming the expectation you beat yourself up against? I'm now sitting on 50% cash as, even though I have conviction in some of my names, I'm too afraid to deploy anything more. Truthfully, I'd be happy to close my account for the year and start again next year. Hopefully this explains my 'out of depthness' and lack of experience.
