my brain was smarter (just not have it bigger one like those aliens with huge, swollen, veiny pulsating ones)
I was unconditionally loved (at least loved back by those I love)
I was drop dead gorgeous
I had more self confidence
I was braver and more daring
I was not so painfully shy and insecure (IRL)
I did not procrastinate
I was more creative
and
I knew when to just let go.
(of course there are randomly more, like having untold wealth; having super powers like being able to manipulate matter >:) [that could be a positive, maybe I'd be able to eradicate world hunger, and create a new environmentally friendly form of energy, turn mean/cruel people into insects, stuff like that]; have time travel abilities;space and perhaps dimensional travel, too; be indestructible [save the cheerleader]; get a kitten and puppy and parrot and Capuchin monkey and elephant...maybe just have a nature/wildlife refuge/preserve; have my ears clipped so I look like an elf; have a holodeck [well, guess with time travel abilities, I could live history so wouldn't really need it, but then things wouldn't necessarily turn out the way I would want, plus all that causing paradoxes and/or anomalies and possibly making things worse, and if it were a fantasy, like being part of a novel, then yes, need a holodeck thoooough, could afford with the untold wealth to have reenactment parties which would be uber fun], oh, and do good things like stop war {turning dictators, warmongers, terrorists into ants let them form their ant armies [hey, I wonder if that is what they are reincarnated as or were?]; and do lots of other good stuff and things.)
