For one day, or for one day for a week, refrain from something you habitually do to run away, to escape. Pick something concrete, such as overeating or excessive sleeping or overworking or spending too much time texting or checking e-mails. Make a commitment to yourself to gently and compassionately work with refraining from this habit for this one day. Really commit to it. Do this with the intention that it will put you in touch with the underlying anxiety or uncertainty that you’ve been avoiding. Do it and see what you discover.
