(Not the person you asked) but it helps to realize that vim in "insert" mode is just like any other text editor you know, you can use your arrow keys and the delete button to edit your document. You will get annoyed pretty quickly navigating with arrow keys and no mouse cursor, so you might search up "how do I jump the end of this damned line!" (hint: it's the $ sign). As you edit documents you will get more and more annoyed and search up more shortcuts which you will be happy to incorporate into your life. This is what worked for me, anyways.
