Improvement
Improvement is the process of a thing moving from one state to a state considered to be better, usually through some action intended to bring about that better state. The concept of improvement is important to governments and businesses, as well as to individuals.
Water
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Strictly speaking, water refers to the liquid state of a substance that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.
Improvement
I do nothing but go about persuading you all, old and young alike, not to take thought for your persons or your properties, but and chiefly to care about the greatest improvement of the soul.
Socrates, Plato's account of the trial of Socrates in Apology. (Translated by Benjamin Jowett.) 30a–b
Water
How sweet from the green mossy brim to receive it,
As, poised on the curb, it inclined to my lips!
Not a full blushing goblet could tempt me to leave it,
The brightest that beauty or revelry sips.
Samuel Woodworth, The Old Oaken Bucket
