You can spend a crap load of time writing up a character description. Age, hair color, whether he's pissed off all the time, whether he's laid back. All that crap. After that what do you have? Nothing in my mind. I've spent some time making these up occasionally but I'm starting to realize perhaps that's what doesn't make a great character. It's what happens to the character and his reaction that makes him what he is. Like Forrest Gump for example. What made me love him was that scene during the Vietnam bombing. It showed he was selfless. I guess my old strategy would be to convince you a character was selfless and now I would rather show and have the reader be the judge. So in short, I think my strategy is going to focus more on creating those situations like that and forming my characters around them.
