Earl of Philip Dormer Stanhope Chesterfield, Letters to His Son, 1746-47
“ The only sure guide is, he who has often gone the road which you want to go. Let me be that guide; who have gone all roads, and who can consequently point out to you the best. If you ask me why I went any of the bad roads myself, I will answer you very truly, That it was for want of a good guide: ill example invited me one way, and a good guide was wanting to show me a better. ”
