Mastering One's Work

I've been reading parts of Booker T. Washington's Up From Slavery this weekend and enjoying the experience quite a bit. I liked this passage, in which Washington talks about how he manages his Herculean workload. It reminds me of a colleague of mine (those who know her will know whom I mean immediately):

I make it a rule to clear my desk every day, before leaving my office, of all correspondence and memoranda, so that on the morrow I can begin a new day of work. I make it a rule never to let my work drive me, but to so master it, and keep it in such complete control, and to keep so far ahead of it, that I will be the master instead of the servant. There is a physical and mental and spiritual enjoyment that comes from a consciousness of being the absolute master of one's work, in all its details, that is very satisfactory and inspiring. My experience teaches me that, if one learns to follow this pln, he gets a freshness of body and vigour of mind out of work that goes a long way toward keeping him strong and healthy. I believe that when one can grow to the point where he loves his work, this gives him a kind of strength that is most valuable.
