I am also considering a real estate fund and an energy fund. I am concerned that I own too many funds without optimal diversification. Maybe I don't have enough solid blue-chip funds. I plan to work for another 10 to 15 years. But I think it's more like a collection of mutual funds and stocks that reflect random good ideas.
Nobody can become a psychiatrist casually.
First you must be a medical doctor, then undergo extensive and rigorous specialty training. The process requires a great deal of time, hard work and careful thought. This tells me you are smart, thoughtful and hard-working. I think that if you fully applied your considerable talents to the field of investing, you would most likely do better than you have. But for whatever reason, I suspect you have not taken the time to think in a disciplined and thorough way about your investments.
