Breaking Social Barriers with the Life Experiments List

I used to do something similar just to see what would happen.<p>For instance one day I decided to hand out roses to random people to see what happened. Another time I spent a day complimenting people on their footwear (well, only if it was worthy of a compliment).

Anyone tried the 'Rejection Therapy' experiment? Seems useful for folks like me who think a lot (and act less) partly due to fear of rejection or failure.
