2019就这样过完了，好像还有很多事情没来得及做，然后就过去了，整的还有很多遗憾，把握住2020的每一天时间吧，望你们的2020年不要浑浑噩噩，要忙忙碌碌、基础、学习、创新、记录、总结、生活都要前进向前看。过程重要结果更重要，不希望N年之后想想之前怎么不努力，薪水怎么不加，这些都是有原因的， 机遇都是给准备着的人的，总感觉这句话有问题，我时刻都准备着呢，机遇咋就是不给我，证明我还是不够努力不够上进呗。加油吧 小姑娘你的人生还很长，驾照还没考，更好的美食还没吃，薪水还没加，钱包还没满，世界各地去的还少，闺蜜还没嫁 
、花呗还没还、房子还没买、车还没买，这么多还没做完的事情，你有什么
颜色相同的代表一对公私钥，本图涉及到四套证书，浅绿和浅粉块的是自己的两套证书，浅黄和浅蓝第三方证书。
