The other main point -- make your own damned decision and do your own research. Show up to flight school with the "please feed me info/guidance, I don't know what to do" and you're done for. The internet is a great tool for sure but wow, does it expose some weak sisters and the "Mr. Helper" guys. Dude, figure it out for yourself.
How about the other guy, Mister I-am-31-and-want-to-be-a-military-pilot, am I too old? Pathetic -- another "feed me, feed me Mommy, I want the info, please anonymous google machine tell me what to do"
All you Mister Helper guys -- just the mil types, step back 20 or 25 years when you were all starry eyed and dreaming, were you as stupid and ill-prepared as some of these guys? "There is no such thing as a stupid question" -- sorry, there is. Some of the questions asked are ridiculous, zero background knowledge, zero research -- lazy, what's with you "helper guys" -- do you not find the lack of preparation sickening?
What a great story for the kids. "Daddy, why did you join the Marine Corps and fight the bad guys? Son, I didn't know what to do so I asked the Great Google Machine for divine guidance, and it was so"
To the OP, if I met you in a bar and you asked me the same question accompanied by the same comments, I would probably laugh -- because you're not serious.
