I've noticed lately that whenever I isolate myself for extended periods of time I always seem to have bouts of recurring social anxiety.

I was advised somewhere to remedy this by simply talking to as many people as possible. My best option right now is to get a job to fill up all of my free time in between classes.

What are some cool social jobs that you've held or can think of that can bring me out of my shell a bit?

I've been a sales associate at a retail store in the past and it really helped me open up to people but I've now shrunk back into my shell of comfort. What are some good options other than retail and why?
