When you take a class or attend a big meeting, where do you prefer to sit? Up close or way back where you can make a speedy get-away? Can you force yourself to focus even when you're not interested?
It really depends on my mood, who is there, who I'm with, etc. If the sound is good I might sit towards the back, but I have bad hearing, so I might sit closer in cases where the speaker wouldn't be loud enough for me to hear.
I cannot force myself to focus if it's boring or I'm not interested, unless the speaker makes me interested.
