Im sort of in the same field as you, I'm a trainee(though they get me to do the same jobs as my foreman's do) at a construction site, you could call it being a carpenter.
Though its tough work, i dont really hate either(but i enjoy my days off alot...like today!)
I actually never would have though to have been sucked into this type of job, since im just out of college with my first year of Graphic Design done.(im not going back seeing how i dont think i will find much joy just doing graphic design yet.), so im working for now(excellent pay and great expirence).
One of the problems(in all jobs) is my foremans, they can be a real pain, but the other guys i work with are fun, we have laughs all the time, and even go get some beer after work :P.
for now, i really can say what i would really want to do, maybe continue in carpentry? or something else,
i found my biggest interest is in music. producing, helping out a live gigs, fixing instruments etc.
