" First, the line of progress is never straight. For a period a movement may follow a straight line and then it encounters obstacles and the path bends. It is like curving around a mountain when you are approaching a city. Often if feels as though you were moving backwards, and you lose sight of your goal: but in fact you are moving ahead, and soon you will see the city again, closer by. "

― Martin Luther King Jr. , Where Do We Go from Here: Chaos or Community?
