I think the real lesson is, don't trade options period. Even if you are not leveraged the odds that you will blow out your account to absolute zero eventually are 100%. Options were never designed to be traded for profit. They were designed as a hedge against price swings in farming. You have to be right about too many things to trade options for profit. It's not possible to do indefinitely and it will catch up with you eventually. Take trading stocks for example. When trading stocks you need to guess direction. That is incredibly, incredibly difficult with any consistency. But when trading options not only do you need to guess direction, you also need to guess direction within a certain time frame. Ridiculously impossible. Oh yes, many, many options 'traders' will tell you with the right methodology you can eliminate one of these variables or reduce one of them to the point of being inconsequential. No. You can't. Ever. It is a hard lesson every options trader learns in the end. Every options trader eventually sings the black swan song when writing out a check for cash against his credit card to refund his account after a blow out.
This is getting off topic but I wanted to respond this is utter crap. There are many people who make a living trading options.
