I'm not sure I understand. But I think my answer is, "yes, I would!"

By that point, hopefully I have enough self knowledge to understand what motivates me and what my true competitive advantages are. I also hopefully have a strong network I can leverage to help me with any blind spots I may still carry. And to spend 5-10 years working on something that I truly am passionate about, which I've worked hard to have the resources to do without encumbering others, sounds rather nice!
