Dear ProDJ26,
Your investment would not be entirely wasted,No knowledge is a burden to carry,but consider that you own a big rig worth say !-2 Million dollars,you have queue of applicants for a job with you...You are just starting out with a course that probably has no real recognition,no experience,and you have the record...Sorry but Truckers have insurances,they carry valuable cargoes and whatever the justice of this,they are just not allowed to employ you...Unless you have money to buy a rig yourself,your options are very limited...Buses are also out because of your record,However the course would help you get a job delivering groceries or Internet Parcels...If you are a sturdy Lad,I think your time would be better spent getting into construction....Wall and floor tiling is a relatively light and reasonable job,opportunities to start with maintenance jobs and work up,try and avoid roofing,too dangerous...Avoid anything to do with Concrete,just grinds your body to bits...Carpentry needs a lot of training..Plastering and Bricklaying take a long time to build up speed and are heavy,dusty work best avoided...But if you can find an experienced Guy in any trade and work cheaply for him,you will have a toe in the door...What about doing a course in plant operation,with a little capital you can easily get a truck and Bobcat!
