Wheel Nut:
A bloke who is 23 has got £30k lives at home and wants to use the money wisely to make a living. Would you go for HGV or something else?
I’d be surprised if you could “make a living” from £30k. It’s enough for some big consumer spending items, but it’s not enough to buy your way out of the labour market.
I wouldn’t recommend it unless he’s willing to take a wild punt on diving into muck and coming up with gold between his teeth.
