Trading Psychology Question

I know it can’t just be me, but do y’all check contract prices after you sell as days go by? Ya know, to see what could’ve been?

I recently make an MU call play. Turned $1000 into $3000. When I check the same strike/expiry, it could’ve been $6000.

Yes. Profit is profit. Green is green. I’m new to options trading and definitely beating myself up.

What do yall do? Do yall maybe sell all but one contract and let the last contract ride thorough?
