At present, many of us will only do what we can do at present, be satisfied with the status quo and not work hard. I don't want to challenge myself and break through myself. I secretly remind myself that I have no ability, I can't! I can't do it! In this way, everything will be done under my own ability, and I will never break through my own ability to do what I can't do now. To break through, you need to take risks; To challenge, you need to pay the price yourself. We should keep trying, learn to challenge, learn to break through, and work hard with what we don't have now. In the future, we will have what we can't have now.
