DeLillo may not believe it, but I do. From the start of the interview:
"INTERVIEWER: Do you have any idea what made you a writer?
DON DeLillo: I have an idea but I’m not sure I believe it. Maybe I wanted to learn how to think. Writing is a concentrated form of thinking. I don’t know what I think about certain subjects, even today, until I sit down and try to write about them."
In a previous life, I became a scuba instructor that kept me in the latest dive gear. (This was along side working towards a Ph.D.)
Eventually it burned me out -- instructing is a stressful "service" gig; and it turned me off of diving for years. This is something that I've observed with other folks in "lifestyle" businesses, e.g., I know yoga and martial arts instructors that ultimately quit not only the instructing, but the hobby.
If you love something, be careful about teaching it!
I settled on snakemake because my corner of bioinformatics had the most prepared 'recipes' for that one, plus it played nice with our cluster's weird local flavor of SLURM
