in basic training your too busy to interact. you will have plenty alone time among people, mainly standing in formation waiting (hurry up and wait)
you learn to get your alone time when your with others.
250k of coverage in education?? someone lied to you, with the new GI bill you will get enough education coverage to go to college for 4 years in a state funded college. you also get paid around 1k per month for living expenses depending where you live (after you get out). you can take as much college as you want while your in but it is difficult because you are going to be busy (depends on your job in the military)
the worst part of the military is being told to do pointless things on a daily basis. you will see better ways of doing things but are unable to do anything about it. Just do what your told and make it through the day.
