If you want to make a difference, you must adopt an attitude of conforming to nature, and you must treat your life with calm thoughts and behaviors. He reminded people that everything is done from small to large, from less to more, from easy to difficult.

It's from Laozi's Chapter 63 of the Tao Te Ching in the Spring and Autumn Period. The original text:

Doing nothing, doing nothing, is tasteless. How big or small, return evil for good. The figure is more difficult than it is easy, because it is finer than it is.

the world's difficult things must be easy, and the world's great things must be done in detail. Therefore, the sage is not great after all, so he can become great. How easy is it for a husband to make a light promise and be faithless? How hard it will be. It is difficult to be a saint, so there is no difficulty in the end.

Translation:

Do the work that others should do before they realize it, do the things that should be done before the accident, and appreciate the smell before it emits. We should treat small signs as major events and fewer signs as many consequences. Treat the resentment of others with kindness. To solve difficult problems, we should plan when they are easy to solve, and to do big things, we should start from small places.

all the difficulties in the world develop from the easy times, and all the major events in the world are formed step by step from the small place. Therefore, saints never do great things directly, so they can achieve great achievements. Promises made easily will certainly be difficult to keep, and taking things too easily will certainly encounter too many difficulties. Therefore, saints should look at it more difficult, so they will not encounter difficulties in the end.

Extended information:

Laozi was born in the Spring and Autumn Period and the Warring States Period. At that time, the environment was weak in the Zhou Dynasty, and various governors were constantly fighting for hegemony. The severe turmoil and changes made Lao Tzu witness the sufferings of the people, which was regarded as the Tibetan history of the Zhou Dynasty, so he put forward a series of ideas on governing the country and protecting the people.

Tao Te Ching mainly discusses "Tao" and "morality": "Tao" is not only the way of the universe and nature, but also the method of individual cultivation. "Virtue" is not the usual morality or virtue, but a special world outlook, methodology and way of dealing with people that a monk should have.
