Motivation for luxury of entertainment

So, this friend of mine decides NOT to enjoy his life. Upon his return from Japan, he has being overly critical in examining his efforts and accomplishment throughout the break. He believes he does not deserve further "slacking off" as he puts it. However, somehow he does not realize that break is created for fun, for relaxation, and for enjoyment. To be overly harsh in thinking about one's workload is defying the very nature of break. Do not get me wrong, I am not suggesting that break means time to give up all responsibility and work, but the ratio must be altered for fun. A movie...won't take up so much time that will inflict damage to the progress. He, in particular, needs to learn that.
