Care to expand? It may depend on your values. Is the purpose of a life to be as productive as possible? Is it to share love with friends and family? We have this sick obsession with productivity that harms our quality of life. Wouldn't you rather make the world happier "wasting" good time with those close to you (even yourself, e.g. video games) than being "productive" for someone else's bottom line?

There are different types of wasting time. I often feel like I overlook hobbies and pastimes that are more productive (reading books, learning languages) over ones that are mindless (browsing HN, watching YouTubes).
