Not equating it to the Navy SEALs, but it's all about mindset. If you can prepare and not break down mentally, you'll make it. A number of SEALs say BUD/S wasn't tough physically, but mentally it'll push you beyond anything else you've ever done, and once your mind is where it needs to be, the rest is easy. I think the same can be said at Alabama. Check your ego, listen, and perform. Much easier said than done, but just like the SEALs, a very small percentage make it.
