I have a classmate who is good at taekwondo, piano, guzheng, cucurbit, calligraphy, painting, oral English and study.

Yes,

But I believe that behind a person's success, there are efforts that ordinary people can't sustain.

As long as you make up your mind. Find the advantages in your life.

Don't feel inferior, come on!

Diamonds don't lose their luster because of tiny flaws, and neither do people.

Give you one more word:

No one is perfect. You may be the next person to win the Nobel Prize in China.

Maybe she is introverted and you are extroverted. Isn't this a great advantage?

Even if she knows more than a little, you must be as good as her.

You can try painting ... a lot.

No one is perfect, and gold is not enough.
