Covered calls strategy - am I calculating incorrectly?

I've been seeing lots of posts about covered calls (CCs) being a decent form of income for MSTR.

I did a quick check and I think I've done something wrong because it seems like you could make ridiculous money with CCs. For example:

I have just over 900 shares, so if I sold CCs on 9 contracts of 100 shares each, expiring in 14 days, with a strike price of, say, $460, I'd earn $2.34 per share (based on options chain of 2 days ago), or $2,106 for a fortnight. If I did that each fortnight throughout the year (so 26 times), I'd have earned about $55k, which is very good money.

Of course, this is assuming my shares aren't called away in a sudden jump, but even if they were, I'd have collected some premium and also had my position improve by 36% (i.e. from $338 to $460).

Am I thinking about this correctly? Just seems too good to be true.

Edit: of course, I'm aware the strike price will have to move and premiums will change each time i sell CCs, but assuming volatility is around this level, maybe more or less throughout the year, it just seems like the premiums with MSTR are amazing.
