My first job was being a shoplifter at Woolworths from aged 8-12.
I thoroughly enjoyed it and found the position quite rewarding.
My Father found out and immediately had me resign my post as a shoplifter (Pogs and Footy Stickers were my main choice)
He had me delivering the Free newspaper in the area, which I wasn't paid directly for but my father implied I was doing this to cover for my expenses such as food and keep (lol)
I then had a weekend job as a kid which was helping my father operate his mobile disco business.
So I'd cart about the lighting equipment, help set it up and so on.
From 16 I was registered self employed, advertising locally fixing pcs /laptops and so on.
