I tried this with my 19 year old cousin and showed her this mental exercise. We came across the local university in the phone book and she mentioned that her student organization was looking to fund raise for an upcoming end-of-the-semester community festival that her university was having.
Having had some experience in flea markets, I knew what sells. I suggested she try buying henna tattoos (that she can easily buy on Amazon for something like $5 per pack) and selling them at the festival.
Well, what happened was that the Student Organization ended making hundreds of dollars that one day. She told me her sorority was swamped with 11 - 13 year old girls lining up to get them; some of them got unruly. I guess there is always a drawback - jaja. Seriously those henna tattoos sell like mad.
Just thought I would share this story about how I introduced one of my relatives to the world of offline marketing
