Referring to this contest thread:

– I’d wish to be able to read people’s minds and get to know about their real intentions (when I want to). Considering that I’m super-smart, that should be absolutely enough to ensure both incredible wealth and happiness for me and significant improvements for the whole society (e.g. when it comes to diplomacy issues).

– I’d wish to be able to control time. If there is one thing that no one can influence but people would give everything for, it’s time. That would also come pretty close to immortality.

– I’d wish to have 24 hours to imagine how exactly I want everything (materialistic) related to my life to look like and then it automatically gets implemented. Have you guys ever imagined how stressful and time-consuming it would be to have everything perfect if money wouldn’t matter? I know this isn’t as crucial if you control time, but it’d still be a pain in the bum. Also you could probably extend this to non-materialistic things so that I’d also set up my own squad of super-attractive and super-interesting women (probably finding those would take up even more time than anything else!).
