Keep an open mind throughout the recruiting process. Think of your choices in terms of Navy, Army, Air Force and the job.
If I wasn't so hard set on being in the Army, when I was young, I might have instead joined the Air Force. Where I would have: stayed in quality hotels and ate in fine dining establishments when I travelled on temporary duty; worked a normal 8 hrs day, not having to go to the field and sleep in the outside in the dirt/snow; not having to carry a rifle and rucksack while on the weekly walk/run with 600 of your best friends in the hot sun/rain/snow; and being able to do physical training at a time that I want instead of at 0700 hrs every weekday morning with a bunch of tired and grumpy men and women.
I hear that the Navy has: big warm ships to work in; nice warm bunks to sleep in every night; three hot meals everyday; hot soup at 1000 hrs everyday; swimming in the ocean when there is time; travel to exotic ports and experiencing new and very different cultures; and really spiffy uniforms (like Summer Whites), that young adults swoon and fawn over.
The Army: works you to the bone; kicks you out the airplane door with a parachute at a dizzy height; screams at you when you're not in step with the group - they really hate that and I speak from personal experience; makes you travel to really awful and desolate places where people are not nice to you; makes you skip meals while on operations; and forces you to keep working for long stretches at a time for days on end. Despite being medically released, I loved every minute of being in the Army.
Oh, to be young again and to choose ... sigh ...
