Character development

A concept every writer should be familiar with is the character idea of Mary-sue and Barry-sue. Most of you will probably already know about this character trap, of making your characters too perfect. They become almost like ultra ego's for yourself and you make them perfect and fantastic versions of yourself that everyone likes, or regrets not liking. There are different types and variations of Mary and Barry sue characters, and thankfully ways of testing how believable or unbelievable your characters are. A friend of mine showed me this great website, you can use it to check the believability of your characters. The important thing is to get people your readers can relate to, real people, with flaws and shortcomings and quirks.
