Job Shadowing Reflection

I thought being a structural/civil engineer would be exactly the same as what it turned out to be. Honestly, it was all pretty boring, and it takes a certain brand of person to do the job because it just looked like an eight-hour workday of torture. Everyday, the person who I shadowed, Mr. Megginson, comes to work in his drury second floor office and deals with the same line of work. His job is to approve bridge drawings and send them to IDOT to be approved. His smaller-classed workers would have made the plans, and then the IDOT plans would be sent to a contractor. His position is more that of a manager and not really a leave-the-office person. This really does not seem to appeal to me because I really would not like to sit in an office doing literally the same thing every day of a twenty, or more, year section of my life. Also, I have already done some research into what I want to do, and mechanical engineering would be more along the lines I am looking for. I did learn about the life of a structural/civil engineer, though, and how I do not want it.
