When you already know something, you can take action against it, so it can’t really hurt you, in that it won’t be a surprise.
However, there are inifnitely more things you don’t know you don’t know, which is guaranteed to have an impact on you. Perhaps if you’re in technology, it’s what you’re not learning that’s going to explode and become common place.
To expose yourself to the most positive outcomes, attempt to expose yourself to as many things that you don’t know as possible.
