I would say that if you are the type of person who feels they need or enjoy more structure in their life, this type of work is well suiting. If you could not see yourself getting dirty, in all types of weather, doing hard physical labor for 40 hours a week, then I would not recommend this type of work. In my experience, in such a position as this it is important to very closely pay attention to the actions and duties of your coworkers throughout the first two weeks. They will impart useful information and skills to you and then once you have a grasp on the typical duties of the job, they will give you greater freedom to operate tools, machinery, or vehicles as their trust in your abilities increases. After this you are able to fall into a comfortable routine that gives your day a good deal of structure.
