A good question, one you should probably consider before you start pretty much anything. What could go wrong? The answer: Pretty much everything,
That doesn't mean you shouldn't do what you imagine doing, but, of course, everything you propose to do includes it's own host of issues, there is a bit of chaos running thru the fabric of the Universe, it appears that we live in a "Quantum Universe," if you want to imagine a God, this God loves to roll the dice.
