More wishes or being able to grant your own wishes is too easy. My wish has the same result as being able to grant wishes or to have more wishes but it will make for a much more interesting life than getting everything you want instantly.
Such a simple wish but it would allow me to do anything I want and I have a to do list a mile long. I would wish to know the answer to ANY question I could think of or be asked. I wouldn't want to know everything because that never ends well, I don't want to change my personality, but I would want access to everything so the solution is to know the answer to any question, lottery numbers, stock prices, access to all information when I need it without the burden of having all the info stuffed into my brain. I would start with simple things to generate some funding for my business to start a serious technical revolution. I would start by making some fast money in foreign exchange which would be used to open a trading room to have many people making themselves rich while generating money for my other businesses that would all make Apple and Google look like Radio Shack. No, it's not about money(at least not after the first couple million $) my goal is to solve the world's problems, cancer, diabetes, aids, alzheimers , the common cold and other diseases GONE, lost or diseased body parts regrown or regenerated, aging reversed or stopped, health maintenance nanites(eat whatever you want and the nanites insure you maintain perfect health and weight). Serious space travel, I'm talking intergalactic space travel, ten million light years in a week, the edge of the known universe in less than 5 years or even instantly if possible, a limitless clean personal power source, and of course transporters(good bye transportation industry), replicators(wish granting machine), hollodecks(fantasy vacations), planetary defense system to stop large meteors and comets, weather control network( to prevent droughts and disastrous storms) rooms that are bigger on the inside(if possible) a self sustaining transportable phone booth sized mansion for everyone. The possibilities are only limited by what is possible and how fast we could advance the technology needed to accomplish our dreams. I would probably build a paradox proof time machine(Observe only, blocks physical interaction with past events and doesn't go into the future past the starting date of the trip) for historical research and clarification only no Back to the Future situations possible.
