If you’re afraid you can’t write, the answer is to write. Every sentence you construct adds weight to the balance pan. If you’re afraid of what other people will think of your efforts, don’t show them until you write your way beyond your fear. If writing a book is impossible, write a chapter. If writing a chapter is impossible, write a page. If writing a page is impossible, write a paragraph. If writing a paragraph is impossible, write a sentence. If writing even a sentence is impossible, write a word and teach yourself everything there is to know about that word and then write another, connected word and see where their connection leads. A page a day is a book a year.
