Time Diminishes What We Require

Time diminishes what we require.
What pain teaches, we learn perfectly.
Each builds a shore around their sea of gladness,
Not losing hope, nor giving way to madness,
Tougher without, within a little shyer,
Yearning always, but settling reasonably.

Often, though, we turn to lovely sadness,
Not willing to let go what we desire,
Even though we want what cannot be.
