I think you should go for it. IMO, being nuts can be a good thing. A goal like that means you have to train for it, eat for it, and do your research/learn what you can to be successful, and you're bound to meet new friends and make good connections along the way. Plus, at the other end of it, you've done something amazing. What's not to like?
