Let not the pleasing many thee delight, First judge if those whom thou dost please judge right. - John Denham

Search not to find how other men offend, But by that glass thy own offences mend; Still seek to learn, yet care not much from whom, (So it be learning) or from whence it come. Of thy own actions, others' judgments learn; Often by small, great matters we discern: Youth what man's age is like to be doth show; We may our ends by our beginnings know.

When any great design thou dost intend,
Think of the means, the manner, and the end.

Search not to find what lies too deeply hid, Nor to know things whose knowledge is forbid; Nor climb on pyramids, which thy head turn round Standing, and whence no safe descent is found.
