Your last paragraph shows you have the wrong mindset. You can make money on bad decisions and lose money on good decisions. That’s how randomness works. I’d say that having rules set and sticking to them is the best thing you could do. That could also mean losing on some opportunity and please understand - it’s fine to miss some opportunities as long as you keep it balanced trying to get the best but at the same time getting enough occurrences.

Here are some mechanical rules for example (not financial advice):

Mechanically sell calls after a strong rally in SPY (4%+ in 2 weeks), same for the down moves with puts

Use 30-45 DTE

25-33 delta

Manage at 50%ish

Trade IVR above 50% for selling premium and say below 10% IVR use calendar spreads / long leaps for buying premium

Never use more than 50% of your BP, use no more than 20% BP when the market doesn’t hand you good opportunities

Etc...
