Correct me if I'm wrong:

what will you do when you feel bored?

Boring and bored have lightly different meaning. 

When I feel boring, I ask myself what is the reason why I'm looking so apathetic and indifferent.

When I feel bored I usually listen to good music, I call one of my friends who has a good sense of humour or I simply get dressed and go out. World outside is so funny just from itself :)

Make sure I am not sleepy. I often think I feel "bored" when what I really need to do is take a nap.

I will get to the bed, grab some snacks, start to playing the PlayStation.

but if that still makes me bored, I will fall asleep with the snacks in my mouth and continue the game in my dream.
*sorry for my joke, please correct my english too.

I would make myself seem more interesting. Then, I would hope that people stop avoiding me.
