Good humor is the health of the soul, sadness is its poison.

Little secrets are commonly told again, but great ones generally kept.

Great merit or great failings will make you respected or despised; but trifles, little attentions, mere nothings, either done or neglected, will make you either liked or disliked, in the general run of the world. Examine yourself, why you like such and such people and dislike such and such others; and you will find that those different sentiments proceed from very slight causes.

Assurance and intrepidity, under the white banner of seeming modesty, clear the way for merit, that would otherwise be discouraged by difficulties...

In business be as able as you can, but do not be cunning; cunning is the dark sanctuary of incapacity.

Knowledge is a comfortable and necessary retreat and shelter for us in an advanced age; and if we do not plant it while young, it will give us no shade when we grow old.

I recommend you to take care of the minutes, for the hours will take care of themselves.
