Don't think that thirty is still very far away from you. When I was twenty, I used to see thirty as a distant future, but now looking back, ten years passed like the blink of an eye. Although I was busy all day without knowing what I was doing, time flew by. I think when a person's life comes to an end and they look back on their own life, they will have the same feeling. From twenty to thirty is the golden age for a person to lay the foundation for their career, and one should always remind oneself: at thirty, can I stand on my own?
