I recommend replacing GUI apps that you use one by one with CLI apps, I started by changing my file manager to ranger. Don’t rush or you may get overwhelmed and don’t interrupt your workflow too much. Next I started using media players, video editors, and even steamcmd to launch games, try to find a replacement for GUI apps searching online. This list is a good place to start;
