I drive for a living. I enjoy it, and it suits me. I've been doing it for 25 years now, though some days it seems both longer and less. One of the blessings/curses of trucking is the time you spend alone. You can't escape from yourself, or your thoughts. This may be the biggest reason so many try and leave the industry. You have to have a high capacity of self-containment to do this job. You have to be able to handle the time alone, with nothing but your thoughts for entertainment. Oh sure, you have a cb radio in the truck, but, take my word for it, there are a lot of, to be polite, weird people driving trucks who talk about some off the wall and sometimes vile things. Also, on the cb, you'll find many who can't speak more than one or two sentences without swearing. 

You will also encounter racists of every color. Whites that use words like nigger, spick, kike, mick, wop, etc. Blacks that hate whites, Hispanics that hate non-hispanic, the whole panoply of human failings are on display. You will run across nice people, and people who should have no responsibility beyond turning on a light. You will run into honest people, and liars and scammers who'll rob you blind if you're not careful. That's just your fellow truckers. We haven't even gotten to shippers, receivers, the DOT, and the company you work for. Oh, and the general public? They don't like you, for the most part. Your size intimidates them, gets in their way and their view. Also, they my have run across one of the miscreants I mentioned above, and, in true fallen human fashion, which we all do to one extent or another, they decided ALL truckers are scum.

Now, if you can deal with all of that, and have the capability to think, not only on your feet, but around corners as well, and be on time, as well as take care of your equipment, you can find that this job can be rewarding. The pay isn't too bad, depending on who you work for, yet, that isn't what I'm speaking of. The reward I speak of is one of knowing that what you do IS important, and has meaning. You will be one of the few who keep commerce moving. If every truck, union and non-union, Owner Operator or company driver shut down, this Nation grinds to a halt. The railroads can't do it all. They are confined to the rails, where we need only ground hard enough to support the weight of the truck. If a road goes someplace, odds are, a truck can get there. So, in that respect, it's rewarding.  

That's all for now. Many thoughts are bouncing, but it's best to start slowly.
