Choosing a Major is Tough

I was originally going to major in biochemistry. Now I'm not so sure. At a school like USAFA, majoring in such a technical, demanding subject like that requires either

A) a person incredibly experienced with that particular field. Basically a natural. A genius if you will
B) a person who wants to work their ass off to try and understand what is to most a foreign language. To do this you will end up sacrificing any free time and every weekend studying.

I am neither of those. I also don't find chemistry that interesting. My goal now is to continue on the pre-med track, but find another major for all other classes. I have less than a month to decide, but here are the ones I am considering.

1) Management (we have one of the most respected undergraduate management programs in the US)
2) Behavioral Sciences and Leadership
3) Biology
4) Economics

Wish me luck. Any suggestions, let me know.
