When I want to slow down the speed of life and leave only the minimum of things that interest me. I remember the verse of Omar Khayyam:

He who understands life is no longer in a hurry,
He watches every moment,
As the child sleeps, the old man prays,
How it rains and how snowflakes melt.
In the ordinary sees beauty,
In the simplest solution,
He knows how to make a dream come true,
