It helps to figure out where you are before you decide where you want to be. For my goal of blogging and tweeting everyday, I've noted how many blog posts and tweets I have today and what the total number of each will be when I reach my goal. That way, it's much easier to keep the end number in mind. Creating a visual like this with those numbers side by side makes it much more likely I'll actually look at at remember those numbers.
