Economics Major?

<p>I'm going to a state school in New York in the fall.
I'm planning on studying computer science as my main focus.
I always want to be an entrepreneur where I develop my own programs and sell it to the world.
However, in order to be a successful businessman, I feel like business skills are vital to me as well.
Do you guys think it's a good idea to double major in economics?
Some people argue that economics major is too "theoretical" and business requires on-hand experiences.
I'm taking AP Economics (both Macro and Micro) this year and I DO feel like economics is somewhat too "theoretical." I don't necessarily regret taking the class because I did learn some very important business-related principles from that class, especially in micro. Had I not take the class, I would probably not know how to think marginally, at least. However, as I said, economics doesn't seem to teach a lot of practical skills that you would need in real life.
My second option is to take a sequences of business classes that I like, such as accounting, finance, marketing, entrepreneurship, etc. However, I'm not sure if I would miss out on anything important from other classes.
My last option would be watching the free online videos about a bunch of business classes and learn the basic core principles of business. However, a lot of those people doing the online videos are not professors or academically accredited, so I'm concern that I'll get the wrong information.
Any idea?
I'd really appreciate it if anyone could give me some suggestions or advises!</p>

<p>Taking a few accounting classes is always a good idea if you want to run a business</p>
