The problem with this argument (and why it comes across as somewhat reductionist) is that it fails to acknowledge the sharp dichotomy between employment and entrepreneurship. The question of working on something for 10 years is less relevant in entrepreneurship, because your role and the nature of what you're working on should be highly dynamic and therefore unpredictable. One should question the mindset instead. Here's what I now tell anyone getting into entrepreneurship to consider: when what you're working on flatlines in 1 to 2 years, do you have the resources and the courage to keep going? I've seen untold numbers of very capable people try their hand at it and then give up after a year or two. That's a waste. And more to the point, it's also a good way to squander much of the value of what you may have learned in the process.
