Boat passengers
Life is really a dream, and human beings are like passengers on a boat sailing along the eternal river of time. Embark on board at one place and disembark at another, leaving other passengers waiting on the other side of the river to board the ship.
Rigid
Most people cannot appreciate the joy of this earthly life because they do not love life deeply and make life ordinary, rigid and boring.
Enthusiasm plus wisdom and courage
Life is cruel, and a person with a warm, generous, and passionate nature may be easily fooled by his more intelligent companions. Those who are generous by nature often make mistakes because of their generosity. They often go astray by being too lenient with their enemies or too trusting in their friends. ... Life is harsh, and a passionate mind is not enough to cope with the environment. Enthusiasm must be combined with wisdom and courage to avoid the destruction of the environment.
