There are no completely happy people, only those who are comparatively more open-minded. Don't overthink things; too much thought will confuse the mind; don't see people too clearly; if you see too clearly, the heart will grow cold; don't get too deeply involved in emotions; if it's too deep, the heart will hurt. Those who are destined to be in your life will leave; things that you cannot change should be let go; the worries and obsessions in your heart should be abandoned. You don't need to be liked by others; just ask yourself if you have acted with integrity, and you don't need others to understand your actions; just do your best. The past is the past, so just smile; the present is the present, so just give your all; the future is the future, so just go with the flow. When the wind comes, listen to the wind; when the rain comes, listen to the rain. In life, being open-minded is happiness.
