Don't have to get upset and thanks for sharing. Folks who cautioned you were well intentioned as there are more loser than winners in this game so it is helpful to hear them out.I don't really care if the stock drops below the strike, so long as the drop is within limits. The only thing I care about is whether there is enough premium on future contracts to roll down profitably. I will often sell contracts at or even in the money to capture the greatest premium. If I need to adjust, fine, that's part of the plan.
But going against the conventional wisdom, I almost never want to hold the stock or take assignment. This is where I differ with the popular "wheel" strategy. I don't like being stuck in a stock that has dropped far below the assignment price. It's too hard to sell calls and then have to play defense on that side when the stock begins to rise.
I found there is a different mindset between professionals (money managers, IB, hedge funds) and retails. For example a drawdown of >50-60% doesn't bother me as a retail and I had quite a few such events happened to me (March 2020 was one by the way).
Someone I know very well trades full time for 15 years using a strategy similar to yours except he is even more concentrated: Only traded options on one stock, selling puts and calls on it over and over for 15 years.
There is more than one way to skin a cat. If it works for you and you are happy, it is your money, go for it.
