Pick realtor. Truck driving is a stupid man job. I'm pretty sure if realtor was an open option, you must have had some fairly good education, enough to be better than driving trucks around the country, never being able to have the time to have a family, or a normal home, or even much time to do anything you really want, because driving across many miles/kilometers will be the most of your time spent. Sure, you'd have lots of time to yourself, pondering about various ideas, but there won't really be any point to them other that to not get bored and to forget the fact that you have absolutely no social life. So, if realtor is an option, I'd take that instead of being a truck driver.
