Restlessness is discontent and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure. Thomas Alva Edison
The sweltering summer of the Negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality.Martin Luther King
