IMO, the only one who can help you is you.
But the best advice I can give you is, if you find yourself consistently growing impatient when playing MTTs, may I suggest taking notes on the players at the table when not in a hand, like physical pencil and paper notes.
This way you can still pay attention to the game while fighting off boredom.
I use a HUD when playing so no paper and pencil for me.
But I do read and post here and also look for pics for my blog while I play to fight boredom, as a matter of fact, I'm playing a ring game as i type this.
