When we attach importance to ourselves, we attach importance to all we perceive as ours. Instead of acknowledging the combination of parts that is ourselves and our lives - all things on loan - each moment becomes more and more appreciated, more and more an opportunity to see past the shroud of things coming together (birth) and falling apart (death).
Living in a disposable culture makes maintaining the things around us less appealing, or meaningful, and this is true for our mental phenomena, as it is true for external possessions. We should appreciate the wholesome things in our lives by not being too exuberant externally, and living in line with our means by looking after what we have. Nor following every impulse our minds have, and being judicious with our actions.
At the end of the day I may be right, wrong, both, or neither. But I am one or the other!
