The past is past, and the future is yet to come. That means the future is in your hands - the future entirely depends on the present. That realization gives you a great responsibility.
There will be no end to the troubles of states,Or of humanity itself,Till philosophers become kings in this world,Or till those we now call kings and rulers really And truly become philosophers
