Detailed Answer
Step 1: Use a keyboard cover (or put a box over your hands). Step 2: Paint or tape over key legends (or use a blank keyboard). Step 3: Learn to find the F and J bumps by touch – practice locating them with eyes closed. Step 4: Use an on-screen keyboard display (e.g., in TypingClub) to see which key you're pressing, but do NOT look down. Step 5: Start with very simple drills (e.g., 'asdf jkl;') while staring at the screen. Step 6: If you cheat, restart the exercise. Step 7: Practice 10 minutes daily eyes-only; within 2 weeks, the urge to look disappears.
