go for it, i decided many years ago i wanted the motor trade, i started as a valeter, ended up selling ont he forcourt, which led to me trading cars, i then got a workshop with a mate, he wa sa painter repaired salvage, i learned off him
i now have a little workshop for me myself and only i, i repair or paint anything, bro inlaw in the workshop next door as a mechanic so i have use of his ramps etc
i also sidlined and bought a recovery truck and set up a website etc, i then sidlined more and got into mileage correction and diagnostics etc
set a task, if your gonna do a trade lean the fucking lot, end result you will be a middla aged man whos fucked the hell off with the motro trade, has no hair left and a slight alcahol problem
