First, select the content. It is easier to write short words about the financial industry, or write an ancient poem about finance, such as five sentences, seven sentences and more than 20 words.
Second, determine the form. After determining the content, choose your favorite book to create. If you don't fully grasp your own personal creation, you can create a word set in related books. Highlights writing is also an art, as long as you can confidently write highlights, it is also a pretty good choice.
