You would be immortal and all basic amenities essential for physical survival would be provided. You can have the age of your body according to your choosing and your mind won’t blow off by accomodating endless amount of memory.
You can choose anything you desire and that too at any instant which may or may not exist in real life, like an endless supply of something or a companion with the same immortality powers as yours, but you won’t be able to change it in the future and there would be no going back. Also you cannot alter your mind in any way that would enable to let you tolerate living for eternity or not get bored of things.
Ideally you would want to have everything just to be sure but by asking you the minimum requirements, it would making it more interesting to know what you think you could do without or what matters to you the most.
I would need a life without the human animal nature to be such a god. I would tire of the hormone cycle. I already find it stupifying to some extent after less than 4 decades. Free my mind of this burden and give me perfect recall to expand my human memory byte. From there I will explore the universe, within the galaxy and beyond.
