I think the words you stop yourself from saying are the ones that will haunt you the longest.

We are masters of the unsaid words but slaves of those we let slip out.

Words can break someone into a million pieces, but they can also put them back together.

The unfortunate condition of the persons, whose labour in part I employed, has been the only unavoidable subject of regret. To make the Adults among them as easy & as comfortable in their circumstances as their actual state of ignorance & improvidence would admit; & to lay a foundation to prepare the rising generation for a destiny different from that in which they were born; afforded some satisfaction to my mind, & could not I hoped be displeasing to the justice of the Creator.

Happiness is pleasure without regret.

By words one transmits thoughts to another, by means of art, one transmits feelings.
