How do designers change careers?

First, it is recommended to learn the software well and choose one from PS or AI. You don't have to learn everything, and you don't have to learn everything. Take PS as an example, you can use a pen, play with layer styles, and draw graphics with Boolean operation of vector tools. The software here is enough for you to get into the business.

Second, don't draw icons in a hurry. Actually, this is a misunderstanding. When you are free, you can draw icons to play and practice your professional skills. However, in practical work, it is really rare that you can draw a group of icons, especially simulated icons. Therefore, I suggest you understand the norms. The specifications of IOS and Android, such as the height of menu bar, the resolution of each mobile phone, how to adapt, the size of keys and the number of rounded corners, need to be understood and used in work.

Third, imitate the interface. There are many apps. Go to the application market, see a good app, install it, then take screenshots and imitate it. When doing it, you can also go to the mobile phone to see why the original app is designed like this, whether it is correct, do it with your own ideas, and find the feeling later. You can modify it.
