How does Percy describe himself? In his view of himself largely positive or negative

From the text:

"I am impertinent," I said.

"I'll be back next summer," I promised him. "I'll survive until then. After all, I am your (Poseidon) son." I asked Argus
to take me down to cabin three, so I could pack my bags for home.

I think he also says that people think he has Attention Deficit Disorder.
