It's sad when someone you know becomes someone you knew.

Make the most of your regrets never smother your sorrow, but tend and cherish it till it comes to have a separate and integral interest. To regret deeply is to live afresh.

Participate joyfully in the sorrows of the world. We cannot cure the world of sorrows, but we can choose to live in joy.

The walls we build around us to keep sadness out also keeps out the joy.

A sad soul can kill quicker than a germ.
