To find out our potential. Many people focus on their weaknesses to the point of forgetting their strengths. (The impact: we often make wrong decisions, and are not confident. And often feel dissatisfied with the efforts we make). Many people think that potential is their subordinate from birth, so many people feel hopeless. In fact, one's potential can be explored and studied. For example, when you do something well, enjoy doing something without pressure, and have your own satisfaction when doing it.
But in essence these three things can be learned. The important thing is that you believe you can change and move forward first, then you will discover your potential.
Occasionally I have heard "searching for identity" often said by parents who are advising their children or young people who are gathered together. I think that sentence is true, we must live with a purpose where finding one's identity is one of the goals in life. It's true what you say we have to have confidence in ourselves first to be able to change for the better then only then can we explore the potential that exists within us to make changes for the better.
