Do you know the four bottom lines of life? This is a required course in life.

The first is the bottom line of life, which is the independence of material and spirit. The independence of material is the foundation of living, and the independence of spirit is the richness of the soul. It is calm and not carried away by the trend, with a poetic heart and distant aspirations, and holding a special skill in hand.
The second is the emotional bottom line. Do not exhaust yourself for unworthy people. Every investment in the emotional world is sincere, but not everyone is worthy. Be sincere to those who are worthy, and stop at those who are not. Ignoring others' feelings is selfish, while caring too much about others' feelings is self-abuse. The heart should be like an umbrella, able to support but also to receive.
The third is the bottom line of being a person, not doing unscrupulous things, not making unscrupulous money. A gentleman loves money, takes it with a righteous heart, and gains something with good intentions. With the intention of benefiting others, one achieves self-benefit. This is not only a kind of self-discipline, but also a kind of peace of mind. Between gains and losses, peace of mind is happiness.
The fourth is the bottom line of life. Life does not belong to you alone, but to everyone who loves you. To live is the greatest bottom line. The essence of life is to be born and live, not to compromise, but to bravely shoulder love and responsibility. May we, on the long road of life, neither lose our original intention nor give up our bottom line. Used to seeing prosperity, eventually return to peace.
