I Remember A Passage In Goldsmith's "vicar

Example Is Always More Efficacious Than Precept.

Now ... That You Are Going To Marry, Do Not Expect More From Life, Than Life Will Afford.

Courtesy And Good-humour Are Often Found With Little Real Worth.

Jesting, Often, Only Proves A Want Of Intellect.

We Are All Prompted By The Same Motives, All Deceived By The Same Fallacies, All Animated By Hope, Obstructed By Danger, Entangled By Desire, And Seduced By Pleasure.
