Can you explain how credit spread work , asking for a friend

gpt
Sell a call a bit out of the money and buy a call one strike further, creating a credit to your account.  The reward is the difference between premiums and the risk is the difference between strikes minus the premiums. Once you are credited the amount, you want the options to expire worthless (which I am phenomenal at choosing options that expire worthless). Time is now on your side with credit spreads.
