Don't be concerned who is watching you. The triumphs and merits of others belong to them - as do yours to you. Make the most of what you've got.

It is no easy thing for a principle to become a man's own unless each day he maintains it and works it out in his life.

There is only one way to happiness and that is to cease worrying about things which are beyond the power of our will.

Does a man reproach thee for being proud or ill-natured, envious or conceited, ignorant or detracting? Consider with thyself whether his reproaches are true. If they are not, consider that thou art not the person whom he reproaches, but that he reviles an imaginary being, and perhaps loves what thou really art, though he hates what thou appearest to be.

You have been given your own work to do. Get to it right now, do your best at it, and don't be concerned with who is watching you. Create your own merit.

You will do the greatest service to the state if you shall raise, not the roofs of the houses, but the souls of the citizens: for it is better that great souls should dwell in small houses rather than for mean slaves to lurk in great houses.

Keep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours.
