Sometimes I use character outlines when I've already created a character so I will remember information about him or her a year or two after I've abandoned a project, and don't have to read through the entire thing before I realize I made a mistake. For example, once I wrote a lifeguard character who said he couldn't swim. Fortunately, it was a quick fix, but character charts can help avoid mistakes like this.
Every character chart is different, and some people like to use different ones. This is just one of many options to use, and I encourage you give it a shot! Click here to go to the original post, and happy writing!
