Rejection Therapy http://www.rejectiontherapy.com is a game that helps people overcome shyness and social anxiety by taking on small challenges. Each challenge increases your comfort zone and your confidence.

I've done the 30 day Rejection Therapy challenge and, while it wasn't easy by a long shot, it did help me immensely. I'm much more comfortable starting small talk with strangers than I was before.

Remember, your comfort zone is elastic. If you don't stretch it, it will retract.
