18 years old looking for advice.

recently turned 18 and have been considering being a truck driver for a few years now. If I get into it now I know I can only go within the state. I'm in louisiana and want to be sure that I can actually get hired after getting a cdl. I've searched this subreddit and the advice given to a bunch of other 18 year olds is to do something else like electrician, welder, etc. What do you guys think?
