I agree with you, you can achieve many things and still be unhappy. Happiness is really a state of mind, contentment brings happiness, self love bring happiness. I love the story you gave, sometime ago in school, I came first, yet I wasn't happy hahaha. That was because the person who usually comes first was my friend, now she can't be my friend anymore and her mummy will beat her. Hahaha. I wanted to remain in my second position. So that's life, different rationale behind happiness 😊
