College plans...

Hey guys, just wondering, at you know, 6:18AM, for some reason..

Do you all think it'd be smarter to go for a dual-enrollment and get a Bachelor's in both Computer Science and Physics at the same time, or would it be more worth my time to drop the Computer Science completely, and go for Astrophysics, which will still land me a Bachelor's in Physics, alongside a minor in Astronomy - which could prove extremely useful in the future, because for years, and YEARS, it's been said, "We need more scientists"...but at the same time, getting a job at a good paying laboratory or observatory may prove more difficult than getting a decent paying job at a local computer store, with only a Bachelor's, so I may have to do awhile of unpaid internship at the science labs, and have some kind of side job for income, right?

Because the way I want to do this, is the right way, and give myself multiple options. I'd like to either get a degree in Computer Science and Business, OR a degree in Computer Science and Physics (or Astrophysics, if the college has a straightforward 'Astrophysics' program, and I only know of a handful that do). With the Business/Computer Science, I'd like to open a computer repair (hardware and software repairs) shop/computer PARTS store that builds computers as well.

With the Computer Science and Physics, I'd just like to leave the CS degree as a leg to fall back on, while I pursue a job at either a university or high school, OR in a science lab (ultimate goal is to be an Astronomer, be able to travel the world and gather data collected at different observatories, and study the universe's past, present, and future) somewhere.

So, with all of this in mind - what do you guys think I should do? Because I think going for 3 degrees at once would be far too overwhelming, and I want to have my degrees by the time I turn 22 - and I just turned 20 in late April this year. Basically just collecting information on what you all think would prove more beneficial to me in the long run, so I can have that float around in my head before picking a major.

Thanks in advance for opinions, guys.
