How do you improve your English writing skills? Do you write many essays? Please, correct :)

In my opinion, it's very important to have good writing skills.Its  an important part of communication. As well as grammar, spelling and punctuation are essential, especially in CV's or resumes, if you want to get a job. The readers from an opinion of you and errors are likely to form a negative impression. Today, when everyone can be their own publisher, we see more and more examples of poor writing skills both in print and on the web. Poor writing skills create poor first impressions. If readers spot a spelling or grammatical mistake, they will have negative reaction on your writing. As just for example, a spelling mistake on a commercial web page may cause potential customers to doubt the credibility of the website and the organisation.
