There was once three black men. One day they were walking on a sandpath and found a lamp. They started rubbing it and a genie came out. The genie granted one wish for each one of them. The first, following his dream, wished to be white. With a snap of his finger, the genie turned him white. Instead of thinking big, the second got jealous and wished to be whither than the first guy, and, with the genie’s magic, he turned white too – as white as snow. The third black man, angry and jealous by his friends' wishes, wished both of them to turn back to their original colour.
At the end, the three black men missed the golden opportunity of their lifetime to effect monumental changes or breakthroughs. They could have asked for knowledge, money or a kingdom to rule, etc etc. but instead succumbed to jealousy and eventually gained nothing
