The sooner we reach this conclusion ourselves!  

(William S. Plumer, "Job's Trials and Mercies")

How vain are all merely earthly possessions!

How unstable is popular favor!

How uncertain are riches!

How soon our pleasures may be followed by pains!

Solomon thoroughly experienced the world. His sober inspired judgment was that all was vanity. The sooner we reach this conclusion ourselves the wiser shall we be.
