1. First of all, it is not recommended to study alone if possible. Sign up for a training class if you have money. It can be much faster under the guidance of the teacher.

2. If the economic conditions are not enough, you can find a set of video materials from the Internet. Now the online resources are doing well, you can find them from the self-study network.

Look around to see if there are any colleagues or friends who are doing development and ask them to give you some advice. Let them tell you what to focus on, which can improve efficiency.

4. If you like reading, you can teach yourself by reading instead of watching videos, but the efficiency may be slower. But it will be very effective.

5, in the process of self-study, do more, and code yourself with the case. Only by doing more can you make rapid progress.

6. Make a study schedule for yourself and develop good study habits at the specified time every day.

7. Cultivate your interest in software development. Interest is the best teacher. With interest, all learning will become active and will play a multiplier role.
