Confidence begets competence
Competence begets confidence
It's a self perpetuating cycle.
The point is to recognise that I said Confidence,
NOT over-confidence or arrogance
Confidence is willingness to try, to work towards, to follow a plan.
Over-confidence is more like skipping steps, being impatient and rushing
Be confident in your ability to follow a plan and develop competence.
That competence then will remove the need for arrogance, hubris, fear and anything other than that quiet confidence of a person who has trust in their ability.
And there's no telling how good that story can get!
