This quote means that many people focus too much on trying to find big, overwhelming moments of happiness, often neglecting to appreciate the smaller moments of joy in their lives. For example, a person might be constantly chasing after a luxurious vacation or a big promotion, and not take time to enjoy small moments throughout their day such as a special cup of coffee in the morning, a walk in the park, or a funny moment with a family member or friend. This is not to say that one should stop pursuing the big things in life, but rather to point out the importance of enjoying the small joys that can bring happiness too.
