I've never found much merit in this approach to situations that you have little intelligence about.<p>The way I see it there are two approaches, you can either ignore the details like the article says or you can try to think it through, find that the odds are not in your favor and still go ahead with it (assuming that you want to go ahead with it). He mentions that you should take the first approach for situations that have little downside. But the risk involved only plays a part when the cost to analyze a situation outweighs the advantage/disadvantage caused by the outcome of the decision. According to his conclusion he is implying that it is not worth doing the analysis before starting a business because the outcome is not worth it which I think is wrong.<p>If we were to look past that and look at the real idea of article, I find that the second approach gives you better chances of success and also has an interesting psychological affect. Using his analogy of looking before you leap; if you were to use the second approach I would expect you to have a better chance landing on your feet. You also have a better chance of not getting blindsided by problems (or using his terms, the rules). This is simply because you were slightly more prepared and you had given the possibilities some thought. You wouldn't be shocked and would be more "quick on you feet".<p>It should also be remembered that if we were to consider the percentage of people that actually take the jump and also look at the chances of success (regardless of the two approaches), it is certain that we are dealing with small numbers and coupling that with the fact that human beings are bad at translating odds into practical actions we have a lot of people that give out such advice. Like somebody mentioned in the comments "Not knowing what you're doing isn't sufficient for success, but it's not sufficient for failure, either.", this applies because the the chances that second approach would increase the odds are small. Even thought the advantage is small I would rather take confidence in the fact that I have done my homework rather than go in blind.<p>There is also one final aspect of people that take the jump; these are people that regardless of the approach they take are clearly in love with what they do. It is easy to underestimate as an outsider the amount of work that goes into doing tasks like starting a business and doing it with passion. It is funny because even for the people that take the jump, they tend to underestimate the work that is put into it since they are having "fun".<p>Since he brings up the QB analogy here, let me share what I always find interesting while watching athletes that perform at the top of their game. They make seemingly impossible throws effortlessly but it is impossible to tell the thought and work behind that single decision by watching them on screen. We will probably never know what went on inside that head while making that throw, for all we know it could have been luck.
