Can you give me some sample how to write advice essay?
I don't have a supply of essays to include here without violating copyrights but there are many samples of advice essays easily found on the internet.
Look in your local newspaper or on any of the popular news service sites. Advice articles on foods and diets are a daily feature on many of them. You might also try "ezinearticles(dot)com for articles on a wide range of subjects.
