How do I keep a track of the Daily Word Count? i.e. if I have a target of 500 Words/day for 5 days, how can I keep a Daily Word Count to ensure that I'm on par with my Daily Target?
If you are doing proper double spacing and margins, you get about 250 words to a page. So for 500 words a day, you need about 2 pages. Rather than words do a page, you will find it easier to keep track of.
If you would like a graphic representation of your daily word count (though you need to input it yourself) I would recommend Word Keeper Alpha. You can track several projects and see your average word counts as well.
Microsoft Word has the ability to tell you the word count. All you do is highlight the text and enable the option (Review|Word Count). I imagine other word processors have a similar function.
