I'm embarking on a reading retreat this week.
When I read a lot of manuscripts in succession some patterns I might have missed if I wasn't reading so much, stand out clearly.
One such pattern: the tendency to describe characters in superlatives. World renowned, elite, billionaire, first dog on Carkoon.
When you really start to think about it, characters don't need to be the top of their field in order to develop the plot.
And when you REALLY start to think about it, the people who are top of the top? They don't have much time for anything BUT the work that got them there.
While novels are fiction, and you get to make all that stuff up, the truth is you want your characters to feel real. And if you've known anyone who is that elite, you know they're all a little crazy. Obsessive even. Focused. As in laser.
The other words for that are: one-dimensional, not fully developed, boring.
Thus if you need a character to be really good at something, just have them be good at it. They don't need to be world renowned. A good point guard, doesn't have to be the best. They can be accomplished without being Olympic level.
Take a look at your characters. Are any of the burdened with superlatives they don't need?
