If it's because you couldn't get it approved the first (few times), then I'm sorry you gave up on it. :(
I think you should just spend some time looking at other hack threads- plenty of them- in Progressing Hacks. Really, it's not that hard to get them approved (unfortunately that was usually taken advantage of, so we have to be strict with what gets approved). As well as checking out other threads, bear in minf what's specified in the Requirements thread. It could be a good source of motivation? I dunno. I'm saying, you needn't give up, but you certainly shouldn't rush it. That's never helped anyone, ever- especially not in ROM Hacking. :)
