(I applied for a raise, but my leader politely refused because of my lack of ability. I want to enter a large front-line factory, but there is no news after every interview. My job hopping plan always fails. Before, I wanted to improve, but I didn't know how to learn. Decentralized and unsystematic learning is very inefficient. Originally, I wanted to follow the trend and develop the whole web stack and made a learning plan, but I gave up halfway because of busy work, poor self-control, no leadership, lack of learning atmosphere and other reasons. If you have the above problems, this course will be your best choice.)
