"When we use our breath to come home and check in, we can catch ourselves before we use a tactic, habit or substance to escape the rat mind. When we catch ourselves before we engage in that habit we can instill this practice: the practice or activity of just observing. Observing silently, without judgment and letting the thoughts pass by." ..."There is no need to have a formal meditation practice, just sit quietly, watch, listen and breath."
From A Quiet Mind
