What’s the feeling behind that?

I’ve been working on some thought downloads and on some unintentional models, but I struggle to identify the feeling behind a thought or even a belief.

Today, for example, I was listening to the call on beliefs, and I identified my belief that I have a limited storage capacity in my brain so there’s just a few things I can learn at the same time before I forget other things. I wanted to do a model for this, but I can’t identify how this makes me feel:

C: I’m learning about project management
T: I have a limited capacity to storage information
F: ?
A: I stop learning
R: I don’t acquire a new skill.

This is just an example, but this happens very often. Could you please help me understand how I can identify my feelings better?
