Why would anyone want to become really good at something?
Why do people sacrifice, scrimp, work hard, cry, sweat, and toil repeatedly to achieve a goal?
The answer to that question can help reveal your own Purpose and Values. And that is really worth knowing.
But go on the journey first to discover your own unconscious/default drives and wishes. Some will be misplaced or dysfunctional.
This is the 'work before the work'.
And this internal journey takes courage - honest self-reflection, asking for feedback, objectivity.
