Running through things because you are familiar with them, breeds routine and this is the seed of boredom.
I don't know why, it's the same reason why you like some music and you don't like others. There's something about it that you like. Ultimately I don't find it's in my best interests to try and analyze it, since it's fundamentally emotional.
The observant Jew has his own sense of values. Torah Judaism is his blueprint for this life, his target for existence.
