Enjoy yourself and live your life in the happiest way for you, and try to help others do the same.
Also butts, tbh.
1. There are loads of anime and games I'd love to be trapped in but like 90% of them would probably result in a quick and painful death for me because there's no guarantee I'd be anything other than some normal guy. Probably something like pokemon which doesn't require special powers on my part to be not-useless.
2. While the odds are in the favour of things not being worse if I pull the lever, inaction is easier. I'd see a distinct moral difference between not saving a guy and actively killing one or two other guys so... Yeah, don't pull.
3. For the sake of efficiency, frustration. Sure, there are some way worse emotions out there that I'd rather not have to deal with but I'm still here, so I know I'm capable of dealing with them, and they all come up WAY less often than frustration. Lots of things are frustrating, it seems like the most common unpleasant emotion so I'm sticking with that.
4. Butts again, tbh.
Just a dimension where I could sleep a lot and lucidly dream so I can sort of forget that I'm all alone. I may not be the most social person in the world but I still like having people around, I'd need some sort of coping mechanism like sleep and dreams to deal with total solitude.
5. Rather learn? Not really, I really enjoy scripting, a lot more than I expected to really, plus it's a cool skill to have. That said, knowledge is cool and I'm always up for learning new things so while I think there's nothing I'd RATHER do, persay, there's a hella lot on the project that looks fun and/or I'd want to improve my skills on. (If you had a magic teaching wand that improved my awful artistic skills and made me a spriter I would so take that.) But yeah, scripting rocks, I'm just happy to learn and feel useful.
