"我一直很有信心。那是因为我有很多主动性。我想要有所成就。"

Simplified Meaning:

This quote means that the person feels sure of themselves because they take action and don't wait for others to tell them what to do. They are driven by the desire to become better and achieve their goals. For example, think of a student who really wants to do well in school. Instead of waiting for the teacher to tell them what to study, they start reading extra books, joining study groups, and asking for help when they need it. Because they take these extra steps, they become more confident in their abilities. In everyday life, you can apply this idea by setting your own goals and working hard to achieve them. If you want to learn a new skill like cooking, you don’t wait for someone to teach you. Instead, you watch cooking videos, try out recipes, and practice as much as you can. By taking the initiative on your own, you will build confidence and improve more quickly. This proactive approach helps you feel more capable and in control of your own success.
