If you are working inwardly, Nature will help you. For the man who is working, Nature is sister of charity; she brings him what he needs for his work. If you need money for your work, even if you do nothing to get it, the money will come to you from all sides.

Let us give Nature a chance; she knows her business better than we do.

So little cost to comprehend that what has long been lawful, over centuries, comes forever out of Nature.

The less you want something, the less you’re thinking about it, the less you’re obsessing over it, the more you’re going to do it in a natural way.

Advice doesn't cost anything - unless you follow it.

I obey nature, I never presume to command her. The first principal in art is to copy what one sees.

Illness or disease is only Nature’s warning that filth has accumulated in some portion or other of the body; and it would surely be the part of wisdom to allow Nature to remove the filth, instead of covering it up by the help of medicines. Those who take medicines are really rendering the task of Nature doubly difficult. It is, on the other hand, quite easy for us to help Nature in her task by remembering certain elementary principles, by fasting, for instance, so that the filth may not accumulate all the more, and by vigorous exercise in the open air, so that some of the filth may escape in the form of perspiration. And the one thing that is supremely necessary is to keep our minds strictly under control. (Introduction)

As in everything, nature is the best instructor.

Don't live by your own rules, but in harmony with nature

Take feedback from nature and markets, not from people.

Nature does not ask permission. Blossom and birth whenever you feel like it.

Nature repairs everything.

As long as we go back often to Nature herself, and practice the art of then forgetting for the time the fictions and hypotheses necessary in the partial treatments of our specialities,—as long as we thereby allow Nature and her facts to speak to us for themselves,—so long shall we, after each fresh contact, return to our labors with renewed strength and clarified vision.

What part should nature play in a work of art? Where should the line be drawn? And from the standpoint of practical procedure - should one work directly from nature or merely study and remember it? Too much freedom frightens me, poor imitator that I am, and yet my head is filled with so many images evoked by what I see around me at all times that nature seems insignificant and banal.
