After a busy day, you can calm down and write a diary. 1. Through today's learning, I found that I have a less understanding of 3D. I lack thoughts on what I have learned before. This is the need to strengthen it. After learning new things, I need to think about what I have learned. " What functionality -> What is achieved -> Why is it realized? If you do it, you will do it too much in the third stage, often do two steps. 2, when you face a lot of things, and everything is more urgent, don't panic. First calm down, arrange the execution order according to the importance of things, then start, don't do this, do it, don't do it.
