What a conundrum

Bizzarrely (if thats even a word) at work today I went from thinking "I have to get another job, this is killing me," to thinking "You know this is actually quite fun and I kinda like doing this." I was trying to work out possible reasons for this. Could it be that work has finally lowered my standards of fun and general living? If so is that even a bad thing? Or could it just be that the pain of boredom has become too much for my brain so it has numbed itself like in a really bad accident? I'm not sure if its a good thing or a bad things that I'm starting to enjoy my job.
