Learning to type fast and accurately will help you in many ways, these are some of the touch typing benefits and advantages:
Save time: This is the most obvious of the advantages; the fastest you type, the more time you will save, and as average, when people learn to touch type, they can type 2.5 faster than when using only two fingers.
Be more productive: When saving time and improving the accuracy, you can simply give yourself more time to spend on other things, or do more in the same amount of time. You will also be able to edit as you go, because as you stare at your screen, you will see errors as they appear.
Improve your health: There are many health issues you can prevent by touch typing. You will become more aware of correct posture when you learn to type properly, preventing your wrists from causing you pain, and as you don’t have to keep looking down at your keyboard, it will reduce neck aching. It will also reduce both mental and physical fatigue when typing for long periods of time.
Improve your focus: As you will not have to look at the keyboard and think about where your fingers are going, you will be able to focus more on what you are trying to say than the actual letters that you are typing. Every time you look down and try to find a key, you are losing concentration.
Find more opportunities: Typing is not an optional skill anymore, many jobs require computer skills and a certain typing speed. Learning to type fast, and to do so accurately, can be one of the most invaluable skills of your career.
