How to have a successful career (fastest/effecient way)

Hi all so I’ve got my practical tests soon, I’m going from car to class 1.

I was just wondering what’s the best routes to go down and what work is the best pay also what jobs have the best working conditions etc. I was also slightly worried about finding my first driving jobs as a new pass so any tips would also be appreciated

I’d like to know what routes you experienced folk have been down, what you enjoyed the most and what’s the best pay etc.

Cheers have a good Sunday
