Advice
My one advice I have from this experience is to not undermine the impact you have on people. The reason I was offered a position at Famous Footwear was because I had worked there previously. I hadn't worked there for two years, but in the event that they needed more help, my manager contacted me directly asking if I wanted to work. If you do your job right, no matter how small or unlikely it is that you'll do it again, people will appreciate the effort and more opportunities can come from it.
