“What nature does in the course of long periods we do every day when we suddenly change the environment in which some species of living plant is situated.”

The form follows the function.

It is not always the magnitude of the differences observed between species that must determine specific distinctions, but the constant preservation of those differences in reproduction.

It is not enough to discover and prove a useful truth previously unknown, but that it is necessary also to be able to propagate it and get it recognized.

All knowledge that is not the real product of observation, or of consequences deduced from observation, is entirely groundless and illusory.

Habits form a second nature.

All known living bodies are sharply divided into two special kingdoms, based upon the essential differences which distinguish animals from plants, and in spite of what has been said, I am convinced that these two kingdoms do not really merge into one another at any point.

It is not the organs-that is, the character and form of the animal’s bodily parts-that have given rise to its habits and particular structures. It is the habits and manner of life and the conditions in which its ancestors lived that have in the course of time fashioned its bodily form, its organs and qualities.

His folly has not fellow Beneath the blue of day That gives to man or woman His heart and soul away.

The Bible talks a lot about thankfulness, and I’m more thankful than I ever was. I try to concentrate on the hundreds of things that go right in a day, instead of the three or four that go wrong.

When you were a kid, a day was a long time and a year was a long time

The challenge to be the best is what drives me and to just improve my body every day.

My end goal is just to do projects at the end of the day that I’m proud of.

In days of doubt, in days of dreary musings on my country’s fate, you alone are my comfort and support, oh great, powerful, righteous, and free Russian language!

Any idiot can face a crisis – it’s day to day living that wears you out.

I had another dream the other day about music critics. They were small and rodent-like with padlocked ears, as if they had stepped out of a painting by Goya.
