When an individual is selfishly engrossed in his/her cause/motive , without any care for others around , he/she suffers from “Cause Blindness”.

This is very harmful for an individual wherein he/she loses sight of own “weaknesses” & others “strengths”.

More often than not this kind of mentality is driven by a finite mindset and can be very detrimental in the long run.

Simon Sinek mentions this in “The Infinite Game”.
