The really great moments descend upon you, they flash by, and flush you, then float away, and disappear into the ether, ungraspable. Sure there is a residue of satisfaction, the warm feeling of the great happiness, but there is no holding onto its flashing beauty. It's a glimmer, a spark, a flame, an instant of perfection, that vanishes so quickly you are not sure it really happened.
The really bad moments can linger, longer. You carry the scar tissue, you nurse the broken bones, or just the deep soul-brokenness. You experience a deep loss as a permanent reordering of the Universe.
So, you know, there is an uneveness in life. The good, the bad, the happy, the sad. There is no math here. You can't total and sum. You just experience what you experience. Hopefully you do it with all your senses and faculties switched on high. That's all you get.
