Overdoing It

'Doing too much all at once - complexity is the enemy of security. Creating individual security groups for each application or user quickly gets out of hand. The continual process of adding access - although granular - without removing unnecessary or expired access results in complex manageability for network security operations and an ideal network for attackers to capitalize on.'

Micro-segmentation is scary
From my experience the truth is that simple segmentation and zoning is very hard in todays environments - people are struggling to separate PROD from DEV in anything but non trivial environments. let alone doing smth that is even close to micro.
The biggest mistake that people make, imho, is that they try to move from 0 to 100 and the comlexity vs. the marginal benefit over a much more modest segmentation goals is what kills the project, unfortunatelly for many years in an organization, once they fail it will take them a long time to try again. And frankly for most organizations it seams so "unachievable" that they do not even start doing it. 
My recommendation is to define modest goals such as separate prod from dev and select ~10-20 of you most cirital apps to ring-fence this achievable especially if leveraging the modern micro-segmentation technologies and you will be in a much much better place from your risk perspective.
