Try to intensify the light in your life, and guard against its loss.
Be nice to your friends, and hope in return they are kind to you.

“Light breaks where no sun shines;
Where no sea runs, the waters of the heart
Push in their tides;
And, broken ghosts with glow-worms in their heads,
The things of light
File through the flesh where no flesh decks the bones.”

Quoted from the poem by Dylan Thomas,
Light Breaks Where No Sun Shines
