Most extra-curriculars are contrivances, designed either explicitly or implicitly to convey some false sense of campus culture to the public at large, alumni, or even the student body itself. I know little of college athletics, so I'll stay away from that category of activity. What's left are a bunch of campus clubs. Since when has the student government had any real power? It either plans homecoming week or takes political positions on issues over which it has no control (like South African politics). Does being student body president get you anything in life? Yup. Those who have an incentive to legitimize this false system might accept you into law school or some other graduate program which can result in real, tangible outcomes. However, you will likely better yourself more by volunteering for a real campaign for a real elected office instead.<p>Fifteen years ago, I was my dorm's food service council representative. No, I'm not kidding! Every month, I went to a meeting where representatives of the firm who contracted with the university to provide food for $800/semester tried to pretend to care what a bunch of kids said about their over-cooked burgers. Actually, they seemed to legitimately care, and I learned a lot from the experience. What I learned was how helpless those managers were when it came to changing the behaviors of their minimum-wage staff. Once, a student said that his dorm-mates wanted more kinds of cereal at breakfast time. Immediately, it was promised that the number of cereal bins would be doubled! Then, when another student wanted the grill to actually be staffed during lunchtime (often, employees would take long breaks whenever they felt like it), management said vaguely that they would consider their options. That they would spend hundreds on frivolity but wouldn't attempt to control their employees left a strong impression on me and has influenced how I consider the behaviors of other managers I encounter in life.<p>Did being on the food service committee help me out in any direct way, like getting a good job? Nope. I would have been better off finding something more real to do where the outcome of my work meant something. Start an on-campus computer repair company, whatever.... I learned more from doing IT work for a small commercial roofing company during a couple summers than I did in any on-campus activities with official, paid advisers.<p>In a nutshell, the contrivances of college life might provide benefit, but the hours spent are less fruitful than those filled with "real" stuff. YMMV if one wants to impress a law school admissions officer or similar.<p>Edit: I didn't really address the "for an entrepreneur" part, but I think my comments still apply.
I'm no entrepreneur, but I think you should consider just finding stuff you enjoy and where you'll meet people with common interests. E.g. if you like dancing, join a dance club. It won't help you out in the future, but once you graduate, its likely you won't have a lot of time for a dance club afterwards.<p>Might sounds a bit cliche, but still, I think that spending all of your college life focusing on your future career is a bit of a waste (thats my opinion anyway).
Debate. Hands down.<p>If you want public speaking skills, you will get them at debate. When I started, I could hardly keep my sentences going the whole time. Very recently I got into the finals of a tournament where we were judged primarily on speaking style.<p>If you want to be able to structure arguments, as you will probably have to do when pitching a startup. There is hardly a better way than trying a billion times, and at the same time seeing how the best in the club do it.<p>Thinking on your feet? You often only have the 7 minutes of your opponent's speech to come up with arguments and your own 7 minutes of refutation. At first you are terrible, but eventually you get to the point where you are never at a loss for something to say.<p>Coming to university with a minimal of social skills and an overload of technical skills, I have ended up getting a lot more out of debate in my first 2 terms than out of the courseload.
I ran a robotics design team. I learned that managing people is not trivial, and I learned it the hard way. I also learned a lot about Linux, embedded systems, and putting electronic circuits together.<p>Another thing I learned was that I strongly prefer working with software to hardware. I am pretty good at connecting components together, but I wouldn't want to design these chips. I ended up switching my specialization, and it's good that I did this then rather than after graduating.<p>My marks suffered, but overall it was worthwhile. I'd still say do something you like rather than what you think will impress a committee. But I don't (yet?) have any incredible success stories to share to back up this opinion.
Just go to everything at first and find what you're interested in. As time goes on you'll settle in to the activities you're most interested in and where you enjoy the company of your fellow participants most.
Depends on your major. If you're a business major, and are thinking of being an entrepreneur in the software industry, pick extracurriculars that are CS-related. And vice-versa.<p>With any luck, you'll be able to meet potential business partners with skill sets that complement yours.
