From the Atlantic, quoting from the Double Helix by James Watson, co-discoverer of the structure of DNA:

My interest in DNA had grown out of a desire, first picked up while a senior in college, to learn what the gene was. Later, in graduate school at Indiana University, it was my hope that the gene might be solved without my learning any chemistry. This wish partially arose from laziness since, as an undergraduate at the University of Chicago, I was principally interested in birds and managed to avoid taking any chemistry or physics courses which looked of even medium difficulty. Briefly, the Indiana biochemists encouraged me to learn organic chemistry, but after I used a Bunsen burner to warm up some benzene, I was relieved from further true chemistry. It was safer to turn out an uneducated Ph.D. than to risk another explosion …

He then went on to meet Francis Crick and the rest, as they say, is history.  Is laziness an engine of success?  Here’s hoping.
