Some thoughts on this.<p>First, thought certainly not a Billion dollars, I came into a substantial (relative to my normal circumstances) bit of cash soem time ago. His #1 point is dead on, it was a mistake I made and regret a lot (see: <a href="http://news.ycombinator.com/item?id=1511200" rel="nofollow">http://news.ycombinator.com/item?id=1511200</a> )<p>In fact all of the advice looks good.<p>Except: "The No-Friends Rule"<p>The premise is sensible, do not donate to your mates, and definitely not to new mates, or old ones you forgot you had. But I don't buy that loaning to friends is a generally bad idea.<p>I lent a fairly substantial amount to a friend because they had run into financial hardship. We called it a loan because they refused to take it as a gift, but I'm not going to ask for it back.<p>One of my other mates has a fairly mad idea for a business that he always (for years) wanted to try. I funded that about 18 months ago and it is currently in the balance between outright failure and setting him up with a business for the next 20 years. Again, not expecting the money back.<p>It is only fucking money. You can enrich other peoples lives with it, so why not. No one <i>needs</i> a Billion dollars, but I know most of my friends could have awesome life changing experiences with a tiny portion of that.<p>So, yeh, don't become a charity... but always give to your friends.
