To eat less…

You must teach yourself how to eat less, but with discernment, insofar as your work allows. The measure of temperance should be such that after lunch you want to pray.

— Saint Silouan the Athonite (1866-1938)

Freedom from anger…

The first step towards freedom from anger is to keep the lips silent when the heart is stirred; the next, to keep thoughts silent when the soul is upset; the last, to be totally calm when unclean winds are blowing.
–Saint John Climacus (c. 525-606)
