Before I was studying CS I worked in a call center for customer support (I now have an internship, thank God). People are relentless thanks to the anonymous nature of the phone. I learned pretty quickly that if I took a walk on my breaks* that my mood would always improve.

To this day I now walk to school and work, and I like to think it's helped make me more creative and introspective. As always, I know that it helps keep my mood up. I really urge people to try to get outside and walk around a bit daily, it works wonders!
