I'm assuming you mean 0.001 BTC and not 1,000,000 BTC
In which case, you need to increase your mining work because with my laptop which has a Nvidia Graphics Card that gives it only 20mH an hour, it's gotten 0.0006 in less than a day. Which means, either you haven't been mining very long, or you need to increase what your mining with. I would recommend spending a few hundred dollars, and trying to get a ~250 mH graphics card system. It's not too good, but assuming you can do it for $300 (not to unreasonable), you will make $1.35/day at the current difficulty, and unless your electricity is ridiculously expensive like mine, you should be able to make your money back pretty quickly.
If you want to know what to do with what you currently have, leave it there and let it grow.
