Reaching a typing speed of 100 words per minute (WPM) requires consistent practice, proper technique, and patience. Here are some steps you can follow to improve your typing speed those are improve your typing skill day by day:

1. Learn Touch Typing: Touch typing involves using all ten fingers to type without having to look at the keyboard. This is crucial for achieving high typing speeds. There are many online tutorials and typing courses available that can help you learn touch typing.

2. Proper Finger Placement: Make sure you're using the correct finger placement for each key. The home row keys (ASDF for the left hand and JKL; for the right hand) are your starting points. Practice placing your fingers on these keys and returning to them after typing other keys.

3. Use Online Typing Tests: Take advantage of online typing tests and typing practice websites. These platforms provide timed typing tests that measure your WPM and accuracy. Examples include 10FastFingers, TypeRacer, and Keybr.

4. Regular Practice: Dedicate time to practice typing regularly. Consistency is key to improving your speed. Aim for daily practice sessions, starting with short durations and gradually increasing the time as you progress.

5. Focus on Accuracy: While speed is important, accuracy is equally crucial. Avoid making mistakes while typing. It's better to type a bit slower and maintain accuracy than to rush and make errors.

6. Use the Correct Posture: Sit in an ergonomic position with your back straight, feet flat on the floor, and wrists hovering above the keyboard. Maintaining the right posture will prevent fatigue and discomfort during longer typing sessions.

7. Use the Right Keyboard: Choose a keyboard that you find comfortable and responsive. Mechanical keyboards are popular among fast typists due to their tactile feedback.

8. Practice Difficult Words and Characters: Identify the words or characters that slow you down and practice them specifically. Focus on improving your speed and accuracy with these challenging elements.

9. Increase Difficulty Gradually: Gradually increase the complexity of your practice exercises. This could involve typing longer paragraphs, practicing with punctuation marks, or typing from unfamiliar sources.

10. Monitor Your Progress: Keep track of your WPM and accuracy through online or offline tool over time. This will help you see your improvement and identify areas that still need work.

11. Take Breaks: Typing for extended periods can lead to fatigue and decreased performance. Take short breaks during typing practice sessions to rest your fingers, your-self and maintain focus.

12. Review and Analyze Mistakes: After each practice session or typing test, review any mistakes you made. Identify patterns in your errors and work on those specific areas.

Remember that improving typing speed is a gradual process, and it's important to be patient with yourself without leaving typing practice. With consistent practice and a focus on word accuracy, you'll see improvements and momentum of skills in your typing speed over time.
