The more obvious ways of communication would be by cell phone or telephone. I use my cell phone every single day and some days I use it before I even step out of my bed. I also use the telephone all day at my place of employment. One an average day I answer about 35 phone calls through my office. These two are the biggest way in which I communicate with the world. I also use email every single day. I use email for my personal reasons and I also use it while being at work.
Another mode of communication that I use from time to time is plain old "snail mail" for letters or cards. Many times when someones birthday is approaching I will send them a card in the mail to communicate to them that there birthday has been remembered. This is not the most popular way of communicating these days but I still use it. I will also occasionally write an old fashioned hand written letter to some of my older family members that do not live close to me. Some of the older generations in my family do not know how to use email so I write them often. It is an old way of communication but I still use it.
All of these ways or modes of communication impact my writing almost daily. When I use email I feel that I can type faster then I can actually write so I tend to get more writing done if it's typed instead of hand written. I also feel that email can even be a more convenient way of communicating instead of a phone call. The person will have the email in a matter of seconds even before they would be able to answer their phone.
I do feel that in some ways, some of these modes of communication are not helping me build better writing skills. When writing an email or text message, I sometimes take the "shorter" way and use incorrect abbreviations for some things. I feel that when I am forced to sit down and hand write something, I write in a more correct way. In the end, every way I use to communicate impacts my writing either in a positive or negative way on a daily basis.
