"就是对自己充满信心"

Simplified Meaning:

Feeling sure of yourself comes from embracing who you are. Imagine a person who loves to paint but is shy about showing their art. When they finally show their paintings, they realize that people appreciate their work. This makes them more comfortable and proud of their skills. Being confident means accepting your unique qualities and being comfortable with them. For example, if you're good at solving puzzles, you don't need to hide it. You can use this skill to help others and feel proud of your ability. Trusting in your own strengths and not worrying about what others think can make you happier. It’s about knowing and valuing what makes you unique and using it to shine in your own way. So, live your life being proud of who you are and what you can do, just like the artist confidently sharing their paintings.
