The frustrating thing is that, at the time, the main reason what I joined for has ended up being not what I thought.
IFS/API/Flight school is not the end-all, be-all of what you were trying to attain. It's all steps on the path. Giving up a shot at Naval Aviation based on a few rides in a fucking Cessna is ridiculous.
or if I might be making a mistake.
You have a slot locked down in the USN. You have NO legitimate idea if this USCG plan is going to work.
But you've appeared to have made up your mind and dropped your pack. There's no shortage of guys waiting to take your opportunity and run with it. And yes, I am an asshole.
