If your goal is to be a good technology entrepreneur, it's probably worth noting that of all of today's technology leaders with entrepreneurial backgrounds, either zero or very few of them actually studied entrepreneurship or business in school (as a major).
If your goal is to be a well-rounded individual, then learning a bit about a plethora of different fields certainly doesn't hurt.
If your goal is to make a lot of money, then a traditional liberal arts education can be your ticket (historically speaking, anyway) to a well-paying, and hopefully otherwise rewarding, career.
If your goal is to learn as much as possible about everything, then you'll definitely feel at home in a liberal arts environment.
It's a very flexible tool for life, and in a very quickly-moving economic climate such as this, flexibility is key, as any recently laid-off Class of 2005-2008 investment banker will tell you.
I’d argue that being well rounded, social, and able to converse on many different subjects will serve you a million times over in your startup. There's far more to building a successful startup than a good idea, design, and code. That’s the easy part and it’ll certainly get you off the ground. But to truly run a successful startup, every aspect of your life and your personality will be tapped. Business by its very nature is a social thing between people and a liberal arts education, and the “college experience,” will serve you well in getting past that first stage and on your way to a legitimate business. If you want to be running things rather than working for someone, you need these qualities.
Disclaimer: I graduated from Yale in 2006 with a Psychology degree after being Computer Science for the first two years. Programming just wasn’t for me. Psychology wasn’t exactly my major of choice (although, lots of it is very thought provoking), but it allowed me the most freedom to choose the courses I wanted.
Why do you say that?
