Agree with Herod.
Although I fell into my RAF career almost accidentally (never thought about flying until very late teens) once in, I couldn't dream of doing anything else.
32 years of continuous flying posts in a variety of helicopter roles later, je ne regrette rien.
Getting airborne in a military aircraft wondering what the poor people on the ground are doing for a living, especially when you break cloud on top and it is pissing down beneath just knocks anything a comfy university town North of London could offer into a cocked hat.
If aviation hasn't captured your imagination after UAS then it probably isn't for you.
Enjoy whatever it is you end up doing and I hope you don't regret your decision if you bang out of IOT.
