As mentioned earlier the best option is to continue with your apprenticeship which will give you a qualification and job history for your CV.
During this time if funds permit then look at doing your Category C with Peter Smythe who offers training over a weekend + a weekday.
Complete your CPC requirements as well during this time.
Try to keep your plans secret from your work colleagues as there is usually in any company a ‘rat’ who will squeal to management!
When decision day comes at the end of your apprenticeship you will then have two options.
Back in 1984 I took my HGV 1 (in those days, no theory tests, CPC etc.) purely as an ambition exercise.
I had no intention of driving for a living as I had a good job in engineering.
However recessions came along and many companies were closing for good.
My C + E licence then became my best lifetime qualification which kept me employed for the next 25 years.
I was also able to return to engineering on a contract basis and when that ended, I could obtain agency driving the very next day if I wanted it.
You are being very sensible in considering your future and Trucknet is a great resource that generally offers good advice.
Good luck.
