剧情介绍

Scientific research has shown that happiness is not solely dependent on external circumstances, but rather, it is largely influenced by our internal mindset. Neurotransmitters like dopamine, serotonin, and endorphins play a crucial role in regulating our mood and overall happiness. By understanding the science behind happiness, we can actively work towards cultivating a positive mindset.
