This is the best way to improve ourself. If you want to learn a new skill, practice is more important than learning. The Internet provides a lot of learning opportunities, but usually we will find that we didn't get more skills. This is because we only reading and inputting information. The key to gaining skills and changing ourself is to keep practicing and keep trying to output.
For example, when we read a book, what you gain the most is not the process of your reading, but when you share it with your friends. Because when we share it, we are forced to think about how this book should be viewed and how to share it with others in an interesting way. This process brings your understanding of this book to a new level.
