The Rugged Individualist
Americans are known for being able to stand on their own two feet. When I was a boy, my hero was John Wayne. He was the epitomy of the rugged individualist. He always knew the right thing to do, and had the courage to do it. America loved "the Duke" and by and large we wanted to be self-sufficient as well.
There's nothing wrong with that idea, as long as it's not carried to the nonsensical level. For example, just because Albert Einstein knew how the basic parts of the universe behaved, he probably would still take his car (if he had one?) to a qualified mechanic. Al knew that there were some things that were outside of his area of expertise. Not only was he great on that E = MC squared thing but he was smart enough to know that he didn't know everything.
When it comes to your financial picture, do you think that you have all of the expertise you need? Do you understand your risk tolerance, and can you make your portfolio meet that tolerance? Many would say "yes." Here's a more difficult question: Are you taking the minimum amount of risk that you need to take to reach your goals? Do you know how to calculate that? Are you familiar with all of the financial solutions that are available to you, and how they work? Do you understand the tax code, and the implications on your nest-egg, as well as your legacy?
In other words, do you know what you don't know?
