yoga with grace

तत्र स्थितौ यत्नोऽभ्यासः

sthitau yatnobhyasa

Practice is efforts to settle your thoughts.

Yoga Sutras of Patanjali, 1.13

tatra = there
sthitau = situate, settle
yatna = effort
abhyasa = practice, repetition

This is much easier said than done!
As well as yoga and exercise, I find drawing seems to help..
What helps you settle your thoughts?
