Your brain and its ongoing factions

One  argues with oneself.
You berate yourself.
You feel good about yourself.
I feel bad about myself.

There is an ongoing conversation 

among the ongoing factions of our brain. 

Each faction competing to control the single output

 channel,  as a a resut the strange feat of 

arguing with yourself, or chastising 

yourself and cajoling yourself.
