Yeah, that is the point. I always think it is wasted time when I have to wait long... You have to keep attention to see what is going on, reading a book just extends your waiting time. At the same time, you come in a bit of a bad mood, but even when not, not many thoughts can flurish. I tried once some audio books, that worked fine and also music. But what without the technical stuff... I wondered if maybe you know some tricks and tweaks...
