Anxiety is suicide, peace is life; worry destroys, serenity upbuilds.

As you want to live, to grow, possess your souls in peace and serenity.

Work, aye, work mightily, powerfully, daily, but work for the joy of it, not because worry drives you to it.

Work persistently, consistently and worthily, because no man can live--or ought to live--without it, but do not let work be your slave driver, your relentless master, urging you on to drudgery, bondage to your counter, ledger or factory, until you drop exhausted and lifeless.

Work for the real joy of it, and then, filled with the blessed trust in God the all-Father expressed as above by Christ, throw your cares to the winds, bid your worries depart, and accept what comes with serenity, peace and thankfulness.
Many proverbs have been written about worry, which it may be well to recall.
