Get two separate and decent financial advisers and lawyers to avoid paying taxes and to how to invest the money wisely (though at the moment the shares don't seem such a good investment), then I'd update my will before telling anyone.

If it was more than 5 mill, for the immediate family, I would offer them each 5% in cash with the understanding proviso that they would never be able to ask for financial requests from me ever again [presented by legal written contract.] Furthermore, if anyone then were to contest the Will, upon my demise or alleged sanity, they would be automatically be totally disqualified from anything from the estate.

(Apparently, 1 in 3 of families, especially with several million in winnings, do try to obtain monies from the winner - either legally or by stealth. In this case money really seems to be the root of all evil, and in these cases it has destroyed whole families through greed and jealousy. Another issue are spouses, who can contest the winnings immediately. Sometimes soon ending marriages and de facto relationships immediately to chase after the loot. After reading some of the court cases in the media, winning money in lotto is more often a curse than a real benefit. Sad. )

If it were more than 30 mill, I would also hire a food taster (just in case) and then hire a Secretary for six months to get all my astronomical things, writings edited, and all my observations into some reasonable semblance of order!!
