It's very good to know how far we can go, and self-esteem plays a key role in this—the value we place on our knowledge, skills, values, and attitudes. When I finished my master's thesis, I knew I could take a step forward, and so I did. I didn't let myself be intimidated, and that's when, five years ago, I became a Doctor of Pedagogical Sciences and a Full Professor. That's life: taking advantage of what it gives us to achieve our goals.
