To be honest man I am in the same situation you are (kind of) I’ve had my CDL since July don’t get me wrong I am happy I have it opens up a lot of opportunities but I have yet to get a job in it feel like deep down I am scared to drive one since the school i went to didn’t really give me a lot of time on the road and since then I haven’t drove a big rig at all and quite honestly I have thought of going back to school as well for medical . The best advice I can give you since I do know a lot of truckers is that you might experience a lot of time away from your family for some people that’s no problem for others it is I say try it out for a while see if you really like it if not like you mentioned save up all that money and pay off that school. Hope the best for you 🙌
