Grammar and Mechanics

I pay attention on grammar and mechanics by revising my writing. Not as often as I would like because of time, but I try to. I look up terms and definitions, and often I go back to the bible: Rules for Writers. In addition, I try to make sure that my writing has some kind of flow and connection, otherwise it becomes disrupted and the reader is unlikely to understand me. I believe that grammar and mechanics are the basic rules set by a group of people or nation so that they can communicate between themselves. And, I also believe that grammar and mechanics changes/ adapts with time. A good example is how people text nowadays, and how people talk in different regions within the same nation, and how people used to talk on the past.
