I liked that I could work with a great group of guys, that my hard work meant something to students, and that I could see the end result of my work and feel good about it.
What I wish was different
I wish my older co-workers were more open-minded in general and less stereotypical in their thinking.
The people in this business for the long run have their certain ways of doing things and care about efficiency. Respect their way of work by blending into it, but don't lose your own personality in the process.
