Above all, do not lose your desire to walk

Above all, do not lose your desire to walk.
Every day I walk myself into a state of well being
and walk away from every illness;
I have walked myself into my best throughts,
And I know of no thought so burdensome that one cannot walk away from it …
But by sitting still, and the more one sits still, the closer one comes to feeling ill …
Thus, if one just keeps on walking,
everything will be all right.

Soren Kierkegaard (Letter to Jette 1847)
