A wise advice.

"Everyday, I walk myself into a state of well-being & walk away from every illness.
I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it.
But by sitting still, & the more one sits still, the closer one comes to feeling ill.
Thus if one just keeps on walking, everything will be all right."

Søren Kierkegaard
