> Most people now want something out of you This is a common mistake, esp among the newly wealthy who are young: The last thing you want is for anyone to know that you are wealthy. There are many ways to make sure people stay ignorant of your wealth. For the people (and dates) that don't know your wealth, then you sure as hell don't educate them by words or bling. For people that know you had an exit, they never saw…
The other piece of advice I always here is that as soon as you have the money, put it away in some safe financial instrument (after you've paid any outstanding debts) for at about a year and keep living your life on exactly the same income you had before you became rich.
Best way to save your money and not go crazy with it? Take responsibility for something. Have something to keep you occupied and engaged every day. Something that depends on your time, care, and attention. That something could be a job you find meaningful and challenging. It could be a child and a family. It could be a big project that you now have the ability to pursue, having come into financial freedom. The point is: have something to focus on other than material.
(Hell, this might even be another company, in which case, even more money flows in. Not the worst problem to have).
We're all familiar with the old saying "A fool and his money are soon parted." Well, in the case of the very smart who happen to come into money, I'd warn "A bored or unhappy person and his money are soon parted."
Money can indeed be a ticket to freedom. But too many people conflate "freedom" with "freedom from responsibility." That line of thinking is dangerous. It leads to boredom and idleness at best, and recklessness at worst.
