You'd have 7 crystals and you'd wish for some Blu Rays? Are you insane? At least you should wish for the absolute luck or talent or the like that, by a byproduct, will continuously bring you in cash. Which as a byproduct will finance every BD you wish. If you're a millionaire I'm sure you could even dictate how your own custom release may look like. oo"
In that vain my first wish might be wishing for the the capacity of absolute usefulness. If you're useful to anything, everybody will need and want you and since everybody is a lot of competition, supposedly one should get some great offers as to who will get unquestioned usefulness, which probably will refinance almost anything of the material world one may ever think of.
(Second wish would after that probably needs to be something that ensures my security though, which bugs me a bit...)
