As a student I much preferred working alone to working on a team — in fact, I dreaded teamwork. Coordinating with other students and working for one final grade just made me nervous.
But after entering the workplace, teamwork wasn't so bad anymore. I found that asking others for help and relying on them to do their part was no longer such a struggle, and discovered that working as a team allowed me to really learn from others. Also, there's a different feeling of accomplishment when you've completed a team project because there's a sense of camaraderie that results from all of your hard work.
