Well, if I go back to the beginning of time, I too have never lost money in the stock market. I took your quote to mean you've never sold any stock at a loss - ever.
As far as the answer to your question - yes, I think stocks are going to hit new highs in the next 10 years.
But, as I've stated before, you and I are in hugely different positions. I'm retired and counting on my retirement savings making up a large chunk of my retirement income. You've got $7 million, with more than half in real estate. You're playing the game to see how much you can possibly accumulate. I have to be more cautious. If the market craters and stays there for 5 years, I'm in trouble - you're probably fine. Ending up with the most money possible isn't my plan.
I really don't know why you can't understand other people's positions.
