Are You Getting a Burst of Dopamine?

When things happen that are pleasurable, or that we feel a sense of accomplishment, that has an evolutionary basis because that's what's going to get us to the next accomplishment. But one of the things that's interesting is the potential of human imaginations to think far into the future, which other species don't do. So if you're trying to accomplish some big task, it's hard to know whether you're making progress on it. If you break it down into these little goals, you will get a little burst of positive feeling. This is the issue of celebration.
