NL is boring?

I play 3/6 and 5/10 LHE, and I recently bought and read Harrington....so all ready to destroy the game I logged on. I thought I would start low and played some 50 and 100 buy in holdem....and I found it boring. This was completely unexpected to me..... Im wondering if this was function of the small pots and bets, or do some people truly find nl more dull then limit? By the end my VPIP must have been getting near 40% from boredom.
