It is amazing how fast people learn when they are not insulated from the consequences of their decisions.” Thomas Sowell "My grandfather once told me that there were two kinds of people: those who do the work and those who take the credit. He told me to try to be in the first group; there was much less competition." - Indira Gandhi
