Owning $mstr is the equivalent of having a job and selling covered calls is your paycheck. You don't need to worry about the price of the stock because as long as you own the shares you have your job and as long as you keep selling covered calls you will keep receiving a paycheck. 

If you ever want a pay raise then just buy another 100 shares, or a multiple of 100 shares, to sell more covered calls. 

Sell the 10-15 Delta 30 days out to keep your job.
