No no, I didn't mean it was boring; I meant it would have been boring if you had left it as is, but since you have it in mind to write more...
It sounds to me as if you're trying too hard. As tempting as it sounds, it is very dificult, and unwise, to try and force ideas. My advice, and personal experience, is to try and forget about. (And I can hear all the readers groaning) Try to get involved in something else, and I'm sure an idea will hit when you least expect it.
In the meantime, I'll try and think of suggestions, and I'm sure everyone else will be happy to do the same!
