I guess I do have something to add.... (what a surprise)
I've been involved in many "sophisticated" investments in my time and they usually just didn't seem to turn out like they were supposed to. With a little selective memory, I pretty much rocked on until I started seeing articles about the benefits of index investing. When I pulled together my returns over a number of years, it was pretty clear that I'd have been much better off asset allocating in indexes.
I'm now in a low stress situation that nets me a better return. I do miss the excitement of a "hot stock" but I'm just about over it. My basic approach now is to worship liquidity and low fees. If I ever get over $5MM or so I might revisit the need for high liquidity in all investments (other than my home).
