Ways in which your fictional characters can let you down...

Have been thinking about the contrary beasts that are the 3 main characters in my draft novel. Technically, they are my flesh and blood. I'm fond of them, but the ways in which they've let me down (so far) include: - 

• Not suiting the names I've "christened" them with (choosing names I like is probably not the best strategy)
• Choosing unsuitable careers (as above)
• Poor taste in men (again, as above)
• Having 'off days' (read: boring!)
• Having personality traits that render them transparent and predictable

Hmm, sounds a lot like myself!
