"Proper equipment in life demands a good memory, likewise the ability to forget" (N.B. Hardeman, Tabernacle Sermons, Vol. 3). We do not always exercise our memories in ways that are best suited to our best development spiritually. We forget those things we should remember and we treasure up those things we should let fly. Someone wrote:

Forget each kindness that you do as soon as you have done it; Forget the praise that falls to you the moment you have won it; Forget the slander that you hear before you repeat it; Forget each slight, each spite, each sneer where ever you may meet it.

Remember every kindness done to you, whate'er the measure; Remember praise by others won, and pass it on with pleasure; Remember every promise made and keep it to the letter; Remember those who lend you aid and be a grateful debtor; Remember all the happiness that comes your way in living; Forget each worry and distress, be hopeful and forgiving; Remember good, remember truth, remember heaven's above you, And you will find, through age and youth that many hearts will love you.
