One of the most effective ways I have discovered to manage the craziness of it all to establish and maintain Commitments. You can start with one simple Commitment; I’ve seen people begin with making their bed every morning.
Some Commitments are particularly beneficial when directly related to the issue.
For example, feeling down and melancholy? Commit to a consistent plan of prayer or meditation. It’s a matter of making the Commitments of greater value than the problems that seemingly drive us mad.
