With any skill, it’s through quality repetition over time that leads to competency.
Only when we’re competent at a skill do we swell with confidence.
That’s because the confidence stems from the work.
False confidence—those who spout what they don’t know as if they do know—might buy some time. It’s a coat of paint over a rotten hull. Eventually the bottom falls out.
The process is slow. But repeat a skill. Practice. That leads to competency. Then people will be confident in you and the loop feeds itself. Your new-found confidence will feed into great competency, which will grant ever more confidence.
