I'm not on the outside looking in, I'm not on the inside looking out
I'm in the dead fucking center, looking around

from Kendrick Lamar (Ft. Ab-Soul) – Ab-Souls Outro Lyrics on Rap Genius

Meaning

This line describes the perspective of Section 80 that Kendrick maintains throughout the album:

He isn’t putting himself on some higher pedestal than the rest of Section 80 (not on the outside looking in), nor is he glorifying the negative aspects of them (not on the inside looking out). He is acknowledging that he is a part of the generation he is addressing and that his music is inspired by what he has observed as a part of Section 80. He’s simply a hip hop journalist; he tells you what he has seen and lets you interpret it as you want.

This could also be a reference to the cover of Illmatic, in which a younger Nas is depicted as being in the middle of the city and looking out at the world.

The world around (i.e. the answers) are dictated by the “world within” or your mind.
