Hi, I first browsed these forums lastnight and tonight felt compelled to join and respond after reading this topic.
Like others have said, I don't think age has anything to do with it either and I believe that it largely depends on the person, people who don't either learn from past mistakes, their own or others. That or they just can't handle the it. If I were to win, say 100 million dollars after taxes I'd not give a nickle to anyone aside my mother and grandmother and the amount I'd give either of them would only be what I'd think they could handle. I don't really like most of my family/relatives so I don't feel complelled to "share the wealth" with any of them, especially after witnessing what they did over the years with my grandmother after my grandfather had an accident and she gained control of the finances, which was a bad thing since she had little to no experience with handling it and they all got in her ear and bled her nearly dry. Same goes to charities from my experineces of witnessing how vulture like many of them can be.
From my own previous experiences, I'd try my damnedest to fight that impulse to buy junk I don't need at least to an extent, much of which I really don't have an interest in in the first place so it wouldn't be a problem and I'm not going to develop new, stupid ones. There's no reason why I couldn't live off a fraction of the interest 100 million dollars would generate. I have no interest in a excessively large home or at this point in my life, buying a home period nor do I have interest in expensive cars or a number of other things. When I invest I wouldn't get over my head and would try to keep it simple. Though there is a part of me that has this idea of a vault filled with gold and platinum... Which would just be asking for robbers if anyone found out about it. I would certainly leave Michigan though and go to one of the states with no state income tax where I'd try to live as anonymous of a life as possible, after getting out of Michigan and being likely exposed as winning.
I can see myself staying pretty much the same, just being able to chase those dreams a little easier and probably being a even bigger nerd. Of course now with saying that, I'd probably end up losing it mentally and financially within five years.
