How very suspicious, Bodine. :P
Have fun being electrocuted, King?
On a more serious note... I'm the same way, actually. I'm never motivated to do anything, and I'm incredibly lazy. I also have a talent for being above average at most things (especially at video games :P), but I rarely excel further in skill. Brawl and Pokemon are the only two things I've highly increased my skill at.
It's ironic... Sometimes I play piss poor, sometimes I play like a tourny pro. I honestly don't know how motivating myself even works.

It's sad, not even understand the innerworking of my mind, isn't it.
Well, anyways, are you possibly getting sick of Brawl, or just getting bored with the same old same old? If it seems like that, just give it a break. Try something new (DEADLY ITEMS ON HIGH!

). If that's not the case, ... you don't have any other advice from me, sorry to say. >.>;
EDIT: Actually I'm thoroughly amused by your DBZ referrences, Bodine.

I've never seen someone pull off as many referrences as me. :P
