It’s appropriate, especially given that this is the time of the year when high school seniors are opening acceptance packets and rejection letters from universities all around the world, to discuss the age old dilemma that many college applicants face: whether to be angular or well-rounded. Certainly it was the raging debate my high school classmates had when trying to sell themselves to colleges. They competed with each other for the most extracurricular activities (speech and debate, business club, sports, volunteering, music, arts, etc.) It became an arms race so ridiculous that we joked that to get into Stanford or the Ivy League, one had to be the captain of multiple sports teams, in student government, get > 4.0 GPA, have perfect SATs, and possess a “major” life accomplishment such as curing a major disease, starting a philanthropic organization, or winning one of the math/science Olympiads.
While being a modern Renaissance man (or woman) can be great for getting into these schools, and it certainly does make for a more interesting person, it’s not a guarantee for finding employment. Employers are looking more for an expert in a particular area, or at most someone with two related and complementary skills.
Just think of it from this approach. If you’re an employer looking at a candidate who has decent skills in finance, accounting, foreign affairs/diplomacy, programming, and photography, you may actually not want to hire that person. One worry is that by spreading him/her self out too thinly, the applicant may not truly be an “expert” in one particular area. Most jobs are defined by boundaries, specificity, and depth (you’re *just* going to crunch numbers), and while breadth is helpful in the upper echelons of management and for insightful business strategists, very rarely do companies recognize that and actually try to hire for those spots. More likely they luck onto a candidate with that vision from hires for other positions. Furthermore, companies like cheap worker drones that fit into narrow holes. A candidate with a diverse skill set is more likely to get bored, leave, or demand higher pay.
Therefore, it’s ok to have side dalliances and hobbies, but if you want to be a top worker bee and advance in a career, you’d better have a profession. Take for example the story of Urs Holzle. He was a pure computer scientist, and as such was able to push the boundaries of his own field, get hired at Google in a senior scientist position, and make bucketloads of money. If he had spent less time in his craft and more in say learning the violin to become “well-rounded” he may not have been as successful as he was.
As a last counterpoint, for those already on the well-rounded pathway, while you may not be the ideal workers, you are excellent entrepreneurs, possessing as you do the strategic thinking capabilities to integrate multiple fields and sense opportunities. Also important in the early days of a startup with limited manpower is the ability to fill and manage multiple business roles.
