Good mental health doesn’t mean that a person is happy and ecstatic all the time.
If that’s the case it could likely mean that you’re suffering from mania. I’m sure someone will write about the different types of mental health issues later on so they will talk more about mania.
Good mental health means being able to manage life’s stresses and happiness in a healthy way, and also being able to reach your full potential in all aspects of life.
Everyone experiences down-times in life. The ability to cope with negative experiences is part of good mental health. However this ability varies greatly from one person to another and, in large part, determines whether people enjoy their lives.
