I'd eliminate corruption in all the world's governments, right down to the local level. People are not sick and starving all over the world because there are no resources available, but because resources are diverted, co-opted, and distributed to those that will compensate the corrupt for personal gain.
See if I could find some way to fail. That would be kind of tough. If you intentionally sabotaged the project you were working on so that it would be unsuccessful, then you couldn't really say you failed when it was unsuccessful. Finding a way to unintentionally sabotage your project is a lot harder than just throwing it in the trash.
I think I'd first have to cruise a lot of seedy nightclubs interviewing folks that have failed relationships for research. Cruising the seedy nightclubs would also give a chance to use some of those great pick-up lines I've learned here on PF.
Oh, and I'd try to create world peace. I want to be Miss Congeniality, too. In fact, I'd even hand out maps to poor people in Tanzangentia.
Ignoring, saving the world, extending life forever, curing all disease, feeding everyone, etc. etc. etc. and strictly in the most exotic personal terms:
I have always wanted a re-entry suit that would allow me to push-off from the space station and eventually land in my pasture. Then again, it would be fun to jump a bicycle off of Phobos [escape velocity ~25 mph], and land on Mars.
