Write everyday

One of the things that sets the good writers from the mediocre or worse is that fact that the good writers write everyday. Even when they are tired and don't feel like it, they sit their butts down in the chair and put fingers to the keyboard or pencils to paper.
The mark of a professional is that they write everyday no matter what they are feeling like or what they are going through in the moment. In fact, for some writers it is the only thing that gets them through the day.
So think about how much you are writing each day and think about how serious you are at your writing. Could you be writing more than you are? Is that television calling you when you should be writing?
Sometimes you just really, really, really, don't feel like writing and in that case, I suppose you can make an exception, like once a year. Just don't get into the habit of taking time off from your writing or that will become more prolific than your writing.
Good luck and keep writing.
