I have said it before and still say... InfoSec is a glorified policy writer. You spent more time 90% of the time "writing documentation" rather than on finding the security problem and suggesting the fix. That's why i choose development rather than InfoSec (despite having a knack for it), because its more technical and i don't need to explain "why" everytime.
I think you are mistaken. Obviously InfoSec is a rather generalising term, while you are abstractly describing the work of someone that works in Application Security.
pentesting? 20% finding the low hanging fruit, 80% writing and explaining your findings.
forensics? 10% finding how they did it, 90% writing and explaining your findings.
malware/policy/security/cloud security analyst? 100% writing and explaining your findings.
the list goes on and on... you are basically and a slave for word processing software, thats why totally understand OP quitting infosec.
