My god, my qualifications don't match my skills or various jobs.
I.left school with nothing (a long story, and my choice!... If ya really want to know ...PM me), I went straight into a catering g college, and gained a few qualifications.
The rest is either filling time, or just getting paid! ....
Security for casual events, sound technician, soloist and singer, stage hand, building work, demolition, teaching, youth worker, photographer, film tech n cameraman, preacher, to name a few.
I've earned loads at times (over a thousand a week) and got paid nothing but a sandwich n coffee.
Most skills were picked up on the job, or were adapted to fit (it's amazing what you can do with the skill set you already have).
