There are a few ways to know when you have completely arrived in life. For instance, when your life story gets to, “then they did that story on me in Forbes…,” you have arrived in life. If you ever do anything aboard your private 200 foot yacht, there is a pretty good chance that you have arrived in life. And when you look in your accounts and honestly wonder what you are going to do with all of that money, you have pretty much arrived. And most of the world probably hates you for that fact, because a lot of people really do not seriously consider the comparative merits of picking up another Bentley versus another Ferrari.
Now, if you are at this level of wealth, you really have options beyond just poring over your potential investments yourself. While you can certainly find the time to do so, and can definitely justify the time spent in such an endeavor, you can also extricate yourself from such messy details and go on to do more fun things. Such is the purview of a life where wealth has finally been attained. Freedom really is its own reward, no matter what all of the wage slaves will tell you.
A lot of people who are where you are have enjoyed investing in Munies – or municipal bonds, to those who can not afford them. And since you have the gilt edged plutocracy thing down pat, you can even afford some Municipal bond portfolio management. Why should you handle all of the nitty gritty stuff all by yourself? What would be the point of being wealthy, if you just owned your investments like some kind of job that you can never escape doing (like a lot of less successful small business owners tend to do in their lives)? Give that up, and let the pros work for you.
