“Our grievances are like bricks we carry on our backs, for the rest of our lives. Sometimes we stop to rest, but we never let go. If someone tells us to let go – to leave them behind – we say ‘no, it’s my brick, I have been carrying these bricks for 15 years, their mine, and I am not going to let go. ” My friend Shai Agassi, Young Global Leader at the World Economic Forum.
