Learn Touch Typing (Stop Looking at the Keyboard)
The single biggest speed boost comes from touch typing — typing without looking at your keyboard. Place your fingers on the home row: left hand on A S D F and right hand on J K L ;. Your index fingers should rest on the raised bumps on F and J keys.
Yes, your speed will temporarily drop when you first switch. But within 1-2 weeks of consistent practice, you'll surpass your previous speed and continue improving far beyond what hunt-and-peck typing allows.
