Life is a process of accumulation, accumulating the trial and errors. Just as what Elon Musk did with the super heavy rocket. The trick for very good ones is, never look for a reason when doing all these kind of things. Look for a reason is nothing more than a sign that you are not patient enough. And accumulating takes time. The less you care about the whys, the more progress you will make in the period of unawareness.
