I like what your doing, because I think it's beneficial any time you prepare ahead of time mentally for possible negative outcomes in the future. You are applying the stoic idea of negative visualization to your financial life.
Here's an example of how I've applied negative visualization to investing.
I try to visualize VTSAX as a stock chart. I'll say something like...ok, suppose it's at $68 right now. And I want to retire in 13 years. Now, suppose that in 13 years it's at $160. And suppose I put 50% of my paychecks towards VTSAX for the next 13 years (which we've been actually doing for a few years now)
Alright, good. Now for visualizing a few scenarios:
Situation #1: I'll draw a straight line in my mind from $68 to $150. If it went completely steady upwards from 68 to 160, Obviously that would be just fine by me.
Situation #2: Now I'll draw a mound in my head from 68 to 150. So lets say over the next 10 years it goes up to 200, then pulls back to 150. I this situation I would be super pumped as it rose to 200, but I'd actually have a smaller net worth at retirement then scenario 1. Why well because I'd have bought fewer total shares each month back when they were super expensive. Even though I was even more excited for the majority of the time in this scenario, I weirdly end up with a lower net worth.
Situation #3: Now I'll draw a valley from 68 to 150. Suppose for the next 7 years it stagnates or goes down to let's say 60, then in the last 6 years it just goes on a tear to 150. Although this cause me to have a lower net worth for most of those 13 years, I'd be buying way more shares than either scenario above. And by retirement I would have a higher net worth than either situation above.
Conclusion: Any month the market goes down, I celebrate that it causes me to buy more shares today, which will cause me to be worth more US dollars later. When the market goes up, I can celebrate that all the shares I bought years ago are worth more US dollars today. So I have reason to be happy either way, but the more and more I visualize it, I am rooting more and more for my stock chart to take the shape of a valley.
