I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
Your experience is the exception rather than the rule. It’s been shown that rags to riches is a myth perpetrated by capitalism. At one time I had your level of success. It was all taken from me when I became disabled. As a Canadian, you have the distinct advantage of at least some social welfare assistance whereas your neighbor to the south has virtually none.
