Yes. You have taken it like a champ. But you didn't seem to learn the expensive lessen of the experience: Diversify except where you have a competitive advantage (e.g. your business). Meaning, make bank with your business each year (e.g. $400,000+ per what you have mentioned m), and sock away $100,000 a year into a diversify financial portfolio for the next 20 years. And by then, you will hopefully be able to sell the business for 8-10 times your net to the next generation, and retire to some low-cost ex-pat paradise like Costs Rica, sitting on a serious pile of cash and living like a king.
Or ignore the lesson and bugger off 50% or more of your potential future wealth jerking around in the market like a gullible noob.
