A revolution is sometimes necessary, but if revolutions become habitual the country in which they take place is going down-hill.

Peoples once accustomed to masters are not in a condition to do without them. If they attempt to shake off the yoke they still more estrange themselves from freedom, as by mistaking for it an unbridled license to which it is diametrically opposed, they nearly always manage, by their revolutions, to hand themselves over to seducers, who only make their chains heavier than before. | Jean-Jacques Rousseau, Discourse on the Origin of Inequality
