Tolstoy's famous sayings include: 1. A person is like a fraction, his actual ability is like the numerator, and his valuation of himself is like the denominator. The larger the denominator, the smaller the fraction value.

2. If a girl wants to marry a rich man, it is not love. Property is the most insignificant thing. Only one who can withstand the pain of separation is true love.

3. Happiness does not mean causing even a small amount of pain to others, but means directly contributing to the joy and happiness of others. It seems to me that it can be most succinctly expressed in this respect as follows: Happiness consists in refraining from evil, in forgiving, and in loving others.

4. All changes and charms in life. All beauty is made of light and shadow.

5. The more difficult and difficult the environment, the more firm perseverance and confidence are needed, and the greater the harm of slacking off.
