There is a portion of the cerebral cortex of your brain folded deep within an area between the temporal and frontal lobes. 

It's called the insula and it's where desire starts. 

The insula is only about the size of a pea, but what it triggers in our bodies, and by extension in our lives, can be epic. 

We'd like to imagine that we're in control, but more often than not, the chemicals in our brain control us. The insula lights up and we're compelled to change our lives. 

Compelled by longing. 

Compelled by yearning. 

Compelled by desire for more.
