january homework

I started my January homework and on the second day we have to fill out “On a scale of 1–10, I believe I’m a ________ because I think I’m________.”
I didn’t get that.
Like I have to put what I think about myself and for me it’s obvious that it will be something good and so it’s near a ten.
I don’t get this part of the exercise. Can you explain that to me?

Also what is the difference between “who am I?” AND “Ask yourself, what thoughts do I think about myself?”
For me the answer to these questions are very similar.

Thanks for helping.
