Author, journalist and political commentator Juan Williams was interviewed for the TV show In Depth (view it here online free) that airs on CSPAN's BookTV. I loved this, so jotted it down onto a scrap piece of paper, which I found while organizing papers.
Question: "Do you find it easy to write about these issues or it is a challenge?"
Answer: "Oh, writing is the greatest intellectual exercise I've ever had. You know my Dad trained boxers. I used to be around people who exercised and had to show tremendous courage under fire. For me, engaging in a book and the ideas, getting those ideas to be real on the page so others can understand and engage in them takes -- it's my maximum energy -- my maximum being."
I can relate to that so deeply that sometimes it brings a tear to my eye. I think what touches me the most is knowing someone else out there gets it, about writing.
