Good luck bro! It's a great experience, and I'm sure you'll have plenty of stories for us when you come back!
don't forget to pack the necessities (should be some YT vids or something)
don't forget shower shoes/flip flops, or you'll be showering in your running shoes (which sucks)
embrace the suck (PT in the morning, terrible chow) just push through it
DO NOT GET ANY SWEETS. they may have a 'carousel' with pies and cake, sometimes soda, just dont. nothing good ever happens.
There is no better feeling than graduation and finally being called something other than "trainee/recruit"
don't eat the scrambled eggs for breakfast, it's powdered shit and makes everybody puke
make sure you know how to shave lol (many of my flight members had no clue how to shave properly with disposable razors)
They will most likely try to shit on your life like they did to my flight (i.e. your parents dont love you, you're here because you didnt get a Bentley for your birthday, etc.) but try your best to ignore it.
The best advice I can give you is: Listen to what they're saying, not how they say it.
Also, random airport hugs are the best, (after graduation flying to different airports to go home or to your next base)
