Yes you have to adapt and I love your definition of adaptation that is;
Adaptation is the master key to unending acceptance, It is not the denial of your difference or uniqueness
But have to gain mastery on his field before he rush out to another.
Everyone has his own unique way of getting things done.
Amazon may be great because he gain masterly faster than another.
So specialisations and doing things you know how to do well is also a key.
This is a great motivational @Ogochukwu
