Sorry to post so much, I am new so please forgive me. To my mind boring is suffering and one should seek to avoid it.
True equanimity, to my mind, comes from overcoming boredom.
I have overcome boredom through constant mutually beneficial interactions with others and the world around me.
Does being mindfulness not teach one to see the world as a child experiencing things as if they were new.
Is there a food you feel you have never liked but may try again? Can you ask someone to explain their view on something so as to better see through their eyes.
It is hard, for me, to become bored when I seek out other people's perspective and learn from the experience. Even a leaf on the ground has many lessons to tell when one considers the larger picture.
Sorry again for so many posts I'll try to put it all in one next time.
