“There are always plenty of rivals to our work. We are always falling in love or quarreling, looking for jobs or fearing to lose them, getting ill and recovering, following public affairs. If we let ourselves, we shall always be waiting for some distraction or other to end before we can really get down to our work. The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still unfavorable. Favorable conditions never come.”
-CS Lewis

Lewis practiced what he preached throughout his life. Let me share some examples:

In midst of bombs being dropped on England, and serving as an air raid warden, Lewis wrote “The Screwtape Letters” and “Mere Christianity”.

In 1954 he worked as a professor at both Cambridge and Oxford. Daily commutes consumed most of his time and yet he wrote “Till We Have Faces”.

Finally, in 1960 as his wife was dying of cancer he managed to document his struggle in his book “A Grief Observed”.

Favorable conditions never came for Lewis, and you could argue that because of these challenges, he produced some of his greatest work. Go and seek.
