Old Dog New Tricks

Hey, well where to start i use to drive trucks for the army but i have been out for 6 years i did some other stuff and i think i need to go back to what i did very well. The only difference now is that is is all money based. I am doing the whole come to our training center we will train you and get you a job. but i am taking it with a cautious approach and not just taking them at there word and it seems to me from my research that you get from it what you give for the most part. any advice yall want to give would be welcomed and appreciated. In advance ty and i will be looking thru these forums for advice and tips and tricks i haven't learned yet.
