Some of the characters you create as an author will be Do-ers who try to accomplish their purposes through activities (by doing things). Other characters are Be-ers who try to accomplish their purposes by working it out internally (by being a certain way). When it comes to the Main Character, this choice of Do-er or Be-er will have a large impact on how it approaches the Story’s problem. If you want your Main Character to prefer to solve problems externally, create a Do-er. If you want your Main Character to prefer to solve problems through internal work, create a Be-er.
