"私たちが実際に持っているスキルではなく、自分が持っていると思うスキルが私たちの感じ方を決定します。"

Simplified Meaning:

How we feel about ourselves often depends more on what we believe we can do, rather than what we can really do. Imagine two people who are new to cooking. One person believes they're great at it, so they feel confident and excited to cook meals. The other person, though they have the same cooking abilities, believes they're terrible at it and feels anxious and stressed when they have to cook. This idea can apply to many areas in life, like sports, work, or school. Confidence in your own abilities can make you feel good and motivate you, even if your actual skills are the same as someone who doubts themselves. This means that boosting your confidence and believing in yourself can help you feel happier and more successful. Practicing positive thinking and focusing on what you do well can improve your happiness and performance in everyday tasks.
