Absolutely agreed that it's an interest level thing. If you have a modicum of ability in an area, combined with a strong interest, it's my feeling that you'll end up doing far better, than if you have strong ability but limited interest. I imagine most of us can identify things that we're good at, yet dislike doing, as well as having activities at which we don't excel, but just love.
Like you, I spent countless hours reading anything I could find online about investing and early retirement. Whenever I joined a new forum, I would read every single post, back to the inception of the site, before even thinking of asking a question. I am not a fast learner, but managed to soak up enough basic investing commonsense, through the very inefficient method of near-constant immersion, and hoping that some of it would sink in. Some of it did, but that's all! Compared to the time and effort I put in, it is shocking how little knowledge I retained. Thankfully, you don't need to know much in order to be able to manage your own retirement finances - you just need to know the right things.
Yes, I was referring to OBGYN. He was very risk-averse. I finally managed to get him to admit/concede that he was comfortable with that fact that the spending power of his portfolio would not keep pace with inflation over time, as that was the trade-off he was willing to accept in exchange for predictability and lack of volatility. I wasn't sure he was initially fully aware of that trade-off.
I definitely hope he's doing well. He was very committed to using his skills to help others in need around the world. What a wonderful thing. I'm sure he has effected long-lasting and positive change for many people in need. We need more like him in the world. I am truly humbled.
