You will ofcourse need to seriously commit to driving. If you feel you are ready now...go for it..and be fired up about it.
You sound like you are still unsure you REALLY want to drive OTR.
You will need to seriously commit yourself to becoming an experianced Driver. That is talking about 1-2 years OTR. Once you have that behind you...the doors of oppertunity open.
You magnify the thing about a Trucker many people fail to see. Trucker's really have to be in control of their life. Trucker's always have the same problems and needs as the rest of society....yet we manage it rolling down the road, with just a couple days at home, from time to time.
No one is going to give it to you. You have to go out there and take it.
Make your decision, commit yourself to it, be confident, and smile...King of the Road.
