You cannot always change what happens,
but you can always change how you think;
even so, it does take on an Inertia of it's own,
and thus takes cultivation and practice
to truly harness and control.

You cannot change how something makes you feel,
but you can chose how you react to that feeling:
try to remember to react constructively;
whether this means making Art,
or working it out with the others involved;
just try not to burn any Bridges,
you've built them for a reason.

You cannot understand a thing
if it is abstracted from a proper Context,
and most things cannot be put into a proper Context
with Language alone;
thus One can only truly understand one's own Experience,
from the Inside, out.

All else is speculation; philosophy:

You can't control what happens,
You can't control when;
You can't control if;
You can't control anything but You;
Alas, for that is the truest Struggle:
to utilize one's Self, harmoniously.
