I would not feel the desire to tell other's about my win at all; in fact, I wouldn't even tell my family at first.
LOL
If the winnings were large enough, I would move. Because the news would get out eventually, so I wouldn't want anyone to know where I was.
Yes, that is certainly something to consider as you never know what will happen once the news gets out.

Once that all was taken care of, I'd have the account invest all of it and I'd live off the interest.

even though this is the right choice to make, hardly anyone makes it. I have seen a lot of people win a lot of money but they all spend it on something frivolous. My own Uncle won like 500000 INR twice and he just spent everything on materialistic things rather than save for the Future.
