He who is content is always happy; endless desires never find satisfaction.

All changes, even the most longed for, have their melancholy; for what we leave behind us is a part of ourselves; we must die to one life before we can enter into another.

You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.

生活就是痛苦，生存则是在痛苦中找到一些意义。
