" It has been my observation that the happiest of people, the vibrant doers of the world, are almost always those who are using – who are putting into play, calling upon, depending upon-the greatest number of their God-given talents and capabilities. "
- John Glenn

The quote suggests that individuals who are using a wide range of their natural abilities and talents tend to lead happier lives than those who do not. According to John Glenn, these people are actively engaged in various activities that allow them to utilize their skills and potential, which leads to greater fulfillment and happiness.

Beyond its literal interpretation, this statement touches on the importance of personal growth and self-discovery. It implies that by exploring different aspects of our capabilities, we can find a sense of purpose and contentment in life. This exploration not only helps us understand ourselves better but also enhances our interactions with others and the world around us. Additionally, it highlights the idea that happiness is often derived from the active engagement and utilization of one's talents rather than merely possessing them.
