Scott Fitzgerald was right about at least one thing: a clean break is something you can never return from as it effectively abolishes the past. And to flee, I would suggest, is to endeavour to make a break of this kind; to leap like a demon from one world into another.
Unfortunately, a lot of people don't seem to understand this idea very well and so fail to value it very highly. They mistakenly believe, as Deleuze points out, that fleeing is a cowardly avoidance of commitments and responsibilities, or marks some sort of retreat into a fantasy life.
But nothing could be further from the truth and, ultimately, nothing is more active than flight. Furthermore, despite what the good people say, it also takes courage to paint your wagon rather than accept the comforts of home.
It should be understood, however, that nothing I have just written necessitates travelling to faraway lands, or even having to move: lines of flight involve journeys in intensity and, if you know how, you can run even when standing still.
There's simply no point in heading for a tropical paradise if you are going to be yourself when you get there. And yet leaving your job, your car, and even your friends and family behind, is far easier than abandoning one's own precious ego and losing or escaping from the face.
