Versatility is a funny concept. Conventional wisdom holds it as a trait to be valued highly; everybody wants to be good at more than one thing, and everybody covets people and things that are useful in more than one situation.
A diverse skill set can make you more attractive to potential employers. Women want a guy sensitive enough to shed a tear during The Fault In Our Stars, but game enough to knock a dude out at a bar if need be.
At the same time, versatility can be a detriment. Being adept in too many areas can foster a lack of focus, or indecision as to what to devote yourself to.
