In time and with water, everything changes.
The moment is timeless.
Movement will fail sooner than usefulness.
The eye - which sees all objects reversed - retains the images for some time.
Even the richest soil, if left uncultivated will produce the rankest weeds.
An artist who lacks the power of self-criticism accomplishes but little. It is good if your work stands higher than your own opinion of it; bad if it is on the same level. But it is a great disaster if your work stands lower than your judgment of it.
