To the man of thought almost nothing is really ridiculous.

In all things, to serve from the lowest station upwards is necessary. To restrict yourself to a trade is best. For the narrow mind, whatever he attempts is still a trade; for the higher, an art; and the highest in doing one thing does all, or, to speak less paradoxically, in the one thing which he does rightly he sees the likeness of all that is done rightly.

He who is wise puts aside all claims which may dissipate his attention, and confining himself to one branch excels in that.

Forget not that the man who cannot enjoy his own natural gifts in silence, and find his reward in the exercise of them, will generally find himself badly off.

There is nothing insignificant in the world. It all depends on how one looks at it.

Things which matter most must never be at the mercy of things which matter least.

Not art and science only, but patience will be required for the work.
