The purpose of all human efforts is to achieve happiness.

Happiness is a fragrance of the soul, the harmony of a singing heart, and the most beautiful music of the soul is compassion.

If pain is exchanged for knowing the truth and adhering to the truth, you should consciously and happily bear it. Then, and only then, will the pain turn into happiness.

True happiness comes from being fully committed to the pursuit of our goals.

True happiness can only be experienced when you truly understand the value of life.

Just as we have no right to only enjoy wealth without creating wealth, we also have no right to only enjoy happiness without creating happiness.

For most people, they are as happy as they believe they are.

If we cannot build a happy life, we have no right to enjoy happiness, just like we have no right to enjoy wealth without creating wealth.

Science is by no means a selfish pleasure. Those who are lucky enough to be able to devote themselves to scientific research should first use their knowledge to serve mankind.

No matter how difficult it is, the struggle for happiness is not a pain, but a joy, not a tragedy, but a drama.
