President Spencer W. Kimball
“Right decisions are easiest to make when we make them well
in advance, having ultimate objectives in mind; this saves a lot of anguish
[during moments of decision], when we’re tired and sorely tempted. …
“Develop discipline of self so that, more and more, you do
not have to decide and re-decide what you will do when you are confronted with
the same temptation time and time again. You only need to decide some things
once! …
“The time to quit evil ways is before they start. The secret
of the good life is in protection and prevention. Those who yield to evil are
usually those who have placed themselves in a vulnerable position” (Teachings
of Presidents of the Church: Spencer W. Kimball [2006], 108–9).
