One of the ways to make people delighted, in my opinion, is increasing interpersonal interactions. Humans are social animals, and we enjoy going to places where quite a lot of people are gathering together. For example, when seeing a lot of people waiting in a long line to purchase something, many people would like to join in the long line without hesitation. Although waiting in a long line would take people quite a lot of time, they none the less enjoy the pleasure of doing something together with an enormous number of people.
Another way to make people delighted is satisfying their sensual desires, and I believe this is the way people like most. Nonetheless, this way more often than not demands a lot of monetary input. The degree of pleasure usually has a lot to do with the amount of money put in to pursue sensual satisfaction. In other words, if we are not rich enough, this is not a recommended way. On top of that, this kind of pleasure usually needs sacrifice of health.
In a nutshell, a recommended way to make people delighted is increasing interpersonal interactions. Since now I do not have to spend most of my time on preparing for examinations, I could have more time to look for ways to increase interpersonal interactions. Henceforth, I would like to see how interpersonal interactions make people feel delighted^_^
