When it comes to circle of competence, i've always thought about that in two different ways. You have a big circle and a small circle. And the big circle is your learning circle. E yourcircle of competence, of learning, should always be expanding. Inside that is a smaller circle, and that's your investing circle. But that also should be expanding, but at a slower pace,. Ah, and i do believe that both should expand, you know, overtime.
