Agree with
Apache702,
I just tell my own experience.
I was FO on shinyjet and noticed that finally, the job was not for me...not the job actually, but i would say the way it's managed. (i was in LCC so !).
so I had to quit and now I'm stucked. I am 31 and never done a degree before. Believe me I still regret it a lot.
As KAG pointed it out, indeed it's not too late to study later on, but it's kind of hard
Fortunately, Im single, Im not married, i don't have kids. Pfeww. Sometimes I imagine myself if I had any family to feed, and would be hard to study in the same time and changing career.
I started flying very young in my teen age, I had never idea that I may change career (for a while at least).
My point is : you never know the futur. so the best thing is to jump in the life with a parachute.
Of course, studying at 40 or 50 or 90 y/o it's always possible but let's face it, it's harder. Especially if you have family and you're alone or else. While you still have your family and parents, it's not a bad idea to take this advantage.
Nowadays, the wolrd of work is tough. We live in a fast world where things change very fast, we live longer etc and many people, do 2 or 3 differents carreer today, so be marketable.
good luck !
