Do you agree or disagree that very clever children are usually happy?

I'd say clever children aren't always happier because intelligence can bring its own pressures. For example, in China, many gifted kids face high expectations from parents and teachers, which can lead to stress rather than joy. I remember one of my classmates in high school who was exceptionally bright-he aced every exam but often seemed anxious and isolated because he felt the constant need to perform perfectly. That said, intelligence can also bring opportunities and fulfillment if the environment is supportive. So, it really depends on how their abilities are nurtured and balanced with emotional well-being.
