If you drive a truck for a living...you will always be 'on the bubble' in hopes of actually getting ahead and its highly unlikely you will see any real financial return that allows you to turn your life forward for you and your family.
As a result, I seriously recommend considering a certified/ticketed trade....
You could do a lot of this prep in the evenings and it would take a couple of years unless you work to challenge any written exams....but...in 10, 15 or 20 years you will not regret it.
There are thousands of quality jobs out there that require certified technical skill, that are going unfilled....from mechanics, to carpenters, to electricians, HVAC (air conditioning, etc) technicians, etc, etc, etc.
There is an entire generation of young people who barely know a hammer from a screwdriver...and seem to have almost no real perception or interest in anything other than a digital job.....this is their loss.
This means there is opportunity for any man or woman who is willing to step in and learn the craft.
Many of these jobs, unlikely digital jobs, can not ever be outsourced to india or china....and as I said, they are going unfilled.
This is an opportunity......but you get what you give.....there is no 15 minute or 2 week training solution to financial success.
Quality skill and craft takes a little more time and a little more effort....but it pays back in spades and is worth the risk.
Good luck either way.
