I decided to quit my job last week since I found out that I couldn't take care of the kids, balance in the company and work on the school project at the same time. A new colleague took over my position. During the handover process with her, I learned a lot from her. Because of working with excellent people, I also discovered my own shortcomings and reflected on them. . She is a PHD, she is rigorous, and what impressed me most was how positive her attitude towards learning was. My learning attitude is to record it in a notebook first, and then ponder it carefully, study it, and ask questions if I don’t understand it, while her method is to try to absorb and grasp as much as possible when learning, ask questions immediately, and sort out her thoughts when she confirms to me whether her understanding is correct. Therefore, she could learn quickly in a relatively short period of time, and used the time after that to practice continuously, deepen her understanding, and consolidated her knowledge. When working with her, I found that her ability to do excel was very strong. If she didn't know what to do with excel, she Google for answers independently, instead of waiting helplessly for help from others. Besides, she could sit in front of the computer for a long time. I asked for a break while she just stretched and continued to work. I admire her ability to learn, focus and solve problems independently. I am so grateful that I could have an opportunity to work with an excellence. And I wish her all the best.
