According to Wijnand A.P. Van Tilburg:
“Boredom puts people on edge: It makes them seek engagements that are challenging, exciting, and that offer a sense of purpose.”
To summarize the research: in order to get through life sanely, you need to have a sense of purpose. If you’re not accomplishing anything substantial, you might feel drained or disinterested, resulting in boredom. Once boredom starts sinking in, your brain will tell you to re-establish a sense of meaningfulness.
