Some good intentioned advise my friend, looks from your profile yer headed down the path to Golden Leg Spreaders. If not disregard.
Quite a few prior enlisted devil dogs in 4.7 years in VT7 had big-ol problem adjusting to flight school life... shed the "grunt/yuk yuk" 'tude that served you so well, and adopt the "when in Rome" 'tude (you'll quickly isolate yourself with the former, makes flight school much tougher)... Keep the hard charging attitude and play off the other Marines there. Yuk when amongst Yuk Yuks, slime less slimelly when amongst squidies.
Yer gonna be older, more experienced at diggin fox holes and marching around in various geometric shapes but absolutelly no better at manipulating the bernoullis on the wings of orange and white aircraft. That is what counts. Best of luck, congrats on gradiation. Enjoy your $67 dollars that looks like $125 '87$ on your LES!
