Emerging is when you use a platform to come into your own. Merging is when you sacrifice who you are to become part of something else.
Merging is what the system wants from you. To give up your dreams and your identity to further the goals of the system. Managers push for employees to merge into the organization.
Emerging is what a platform and support and leadership allow you to do. Emerging is what we need from you.
