Recognizing that you once held a belief and that now this belief is changing, is the essence of learning.
And by the time you attain that essence, you won’t need the extrinsic validation from an “A” letter grade, a raise, a promotion, or any other validation that you believe extrinsically motivated you to learn in the first place.
To go a step further, you won’t care if the validation for the learning comes or not, from an external source.
And you won’t need reassurance about the actions you take to implement and execute on your newly acquired self-knowledge.
