Revolution is not something fixed in ideology, nor is it something fashioned to a particular decade. It is a perpetual process embedded in the human spirit.
A good traveler has no fixed plans and is not intent upon arriving. A good artist lets his intuition lead him wherever it wants. A good scientist has freed himself of concepts and keeps his mind open to what is.
Don't let yourself be weighed down by what other people think, because in a few years, in a few decades, or in a few centuries, that way of thinking will have changed. Live now what others will only live in the future.
In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot.
