That is good that you would still want to be working after the mega-millions came pouring in. Most folks would just hang it up and let someone else do all the work while they loafed about partying and travelling, at least till all the money was gone.
You know, I really don't know what I would do if I won the lottery (especially since I never buy a ticket), but assuming I did buy one and won, I probably wouldn't do much different than I am doing now. I would give a generous portion to all my kids and grand kids so they could live debt free (but not so much that they wouldn't have to work) and set up a trust fund for all future generations to have a good education.
As for toys, I have all I need and more but, Maybe some more land would be nice with a nice summer cottage somewhere it is cool in summer by a nice lake up in Canada would be great. Of course if I did that, I would have to have another boat to fish in and maybe another RTV to run around the property with, but that would be about it.
