I wonder if the reason it's hard is because that's a 'new path' for your mind? I know for me it's much easier to fall into depressive modes and thoughts and quite hard for me to see the lighter side of things even if they're right there in front of me. This is because my mind has bad habits. I have to re-train it.

Anytime we repeat a motion or a thought, we're using neural pathways in our brain. We need to process bad stuff to get it out and into the open and not let it 'drive the bus' but we also very much need to talk about accomplishments and good feelings in order to reaffirm those feelings and those pathways too!

I always consider it good practice to talk about the good stuff, not because of what A T thinks but because talking about it helps to verify in our minds that good stuff happens too.

It's self-positive reaffirmation.
