In order to do self-destructive things, human beings need to have belief systems that ‘make it okay’ to self-destruct.
Sure, in some way filter of filters may seem like endless.

And when you see your patterns of behavior, you already started to change them in way, that`s more comfortable to you. And that endless tunnel, the road so far, becomes effortless.
