Dietrich Bonhoeffer

No one ever said learning was to be easy, but it's part of the process of evolving as a human being, and we all have to go through it. When I look back, I see that each difficult time brought an important lesson. And I prefer to look at it with gratitude because I wouldn't be who I am today if I haven't gone through it all.

I can well imagine that certain writers, even writers that we'd consider today very great writers, may not necessarily have tested highly on IQ just because of their numerical skills, or maybe they may not be very good at memory, and are not particularly good at these kinds of tests.
