The simplest explanation is not always the right one, truth is very often not simple. (Sigmund Freud, founder of psychoanalysis)

We sometimes apply the acronym KISS, (Keep it short, stupid) to long-winded speakers. But it also applies when you change short to simple. Life has become very confusing for many, so we’re often looking for simple answers. Freud is right, however; truth is not always simple. The deep questions of life require effort to understand and apply.

True wisdom is not a simple matter. (Job 11:6)
The prudent carefully consider their steps. (Proverbs 14:15)
