Question: How can I practice my writing?
Answer: Try writing ten minutes a day. Use one of the hundreds of topics published previously in this blog. You will develop the habit of and a facility with writing.
Try "Flash Fiction." Write a short story in 55 to 100 words, not counting the title which should be no more than two words. This idea came from Harvey Stanbrough. The Writer (Jan. 07), 34-37.
You will find an extensive list of topics for writing used by the SAT at ftp://ftp.ets.org./pub/toefl/989563wt.pdf.
Type the word quotes into Google, select a quote that causes you to want to express yourself and write for ten minutes.
You will be amazed at how writing will become almost a habit, almost as natural as speaking and reading, from spending just ten minutes a day in writing.
All the best. RayS.
