They say you can run from things, but you can't run from yourself.
The cons of running from yourself are quite simple to argue, yet still as valid as the pros. God, I love paradox. Running fom one's self is quite easy: starting with substances that can alter one's state (alcohol, drugs), continuing with self conditioning (includes the state of denial) and ending with therapy - catharsis is said to purge all that's been ballast and provide a thrust to get on with one's life.
So far, so good, only this cannot go on forever (of course, excepting the cases of death over abuse of substances). Sooner or later memories will strike as entities from another planet. The strive for oblivion proves ineffective, so, back to square one.
Plus, all this can take such a tremendous quantity of energy, that it may appears to be more more comfortable to agree with the pros of this argument.
So, where's the freedom in either, some of you may ask? Freedom is in here and now. Face the music to its most dire consequences, be completely aware of every action and you'll be able to carry one without any damage. Remember I said the mind has the amazing ability to cling to fair memories as opposed to grim ones?
The struggle may take a bit of time, but the outcome is worth every penny.
