Recommend Books on Skills
I would like to read a book similar to "Word, Excel, and PPT Office Applications from Beginner to Master". I want to learn some skills to make money, but my wallet is a bit tight. I hope you can recommend some free skills learning materials. They are good for everything, including handicrafts and making.

He moved forward steadily every step because mathematics gave him direction.
