If you are careful to the end as you began, nothing will fail. This is what the sixty-fourth chapter of the Tao Te Ching says. It means that if you are as careful at the end as you were at the beginning, there will be no failure.

Appreciation of Works
"Tao Te Ching" mainly discusses "Tao" and "De": "Tao" is not only the way of the universe and the way of nature, but also the method of individual practice, that is, cultivating the Tao. "Virtue" is not morality or virtue as we usually think of it, but a special worldview, methodology and way of dealing with people that are necessary for ascetics.
Lao Tzu’s original intention is to teach people how to cultivate Taoism. Virtue is the foundation, and Tao is the sublimation of virtue. Without a foundation of virtue, it is very likely that one will fail in conducting oneself in society, running a family, and running a country, and one will not have the ability to "cultivate the Tao." Therefore, cultivating "virtue" is to create a good external environment for cultivating Taoism, which may be what people need; ascetics need to have a peaceful state of mind and a transcendent life, which is also indispensable for "virtue". The moral part of the Tao Te Ching occupies a large part of the scriptures, which is the basis of Taoism.
