Psychologically, the choice 'to think or not' is the choice 'to focus or not.' Existentially, the choice 'to focus or not' is the choice 'to be conscious or not.' Metaphysically, the choice 'to be conscious or not' is the choice of life or death.

Just a thought. How come when you don't make any arrangements you can run into whoever and wherever just by pure accident. Vice versa, when you're thinking non stop on how badly you need to see someone, you invariably end up in different parts of the globe. Sod's law.
