Utility Maximization: Money spent on goods is to utility as time spent on activities is to what?

Utility maximization is all about getting the most satisfaction from what we spend our resources on, whether it's money or time. When we talk about money spent on goods leading to utility, we can think of utility as the happiness or satisfaction we gain from those goods. Similarly, when we spend time on activities, we seek to maximize our satisfaction or enjoyment from those experiences. For example, if you spend your Saturday playing video games instead of studying, you might feel happier because you enjoy gaming more than studying. Just like with money, we want to use our time in ways that give us the greatest pleasure or benefit.
