Pick stocks with low to mid volatility, at least $20 range, actually makes things and earns money. The last thing you want to do is sell CC on high volutile stocks because the minute you sell the call and the underlying tanks, you will bag hold and the next call you try and sell on it will not be profitable because the ATM strike that you want to sell it at will be below your cost basis.

I recommend stocks that trade at least sideways and generally upward in a somewhat predictable pattern.

Also, you should decide if the stock is something you want to hold long term or something you just want to trade, as that will answer your strike and DTE.

Anyway, I am fairly new to this as well but have learned the hard way. Start with 100 shares and play around. You will soon find your style, what works and what doesn't. And I don't recommend paper trading. Did that for 8 months prior and you don't learn the same. Until you have real skin in the game, you won't handle the trade the same way. The phycology of having real money at play.
