Call me old fashioned, but I still think there’s a great deal of merit in doing some research before getting involved in something that’s bound to eat up resources. Especially when that endeavor is likely to be a major consumer of that resource. With joining the service, that would be time. Consider giving yourself the chance to get ahead of the curve by reading a bit ahead of time. Here’s some material that I read beforehand that was either helpful or motivating:
The truth is, looking back, there’s not a lot of leadership like this book illustrates anywhere in the world. While it’s in greater abundance in the military, this book gives a good idea some of the principles you should start developing if you’re interested in pursuing leadership roles while you’re in. Excellent, excellent book.
An anecdote (personal story) of one soldier’s experiences becoming an Army Ranger. Uplifting, with a few spiritual overtones. By no means does that disqualify this book as a low quality read. In fact, it’s a great one. Very honest with none of the pretense that many religious people put on. Very down to earth.
A must have for anybody joining the military. Naturally, you’ll be given a copy of this at Navy BMT, but pick up a copy and internalize a bit of it before hand and you’ll be good to go.
