I went on a self-reliance kick after the last crash in 2008-2009. I didn't lose my job, but my boss lost his, and I had to lay off 2/3 of my department. All of a sudden, almost everyone around me at work was gone.
After that, I did a self audit, and itemized the "fragile" things in my life...what did I worry about?...what was fine now, but could change easily?...what was unlikely to change but would have major effects if it did? I then started aggressively addressing each one of them. This has allowed me to be "less miserable" about recessions, social tensions...even less likely things like potential social upheavals. [Edit to add this along the lines of your comment below: I felt a sense of purpose from being a husband and father, and taking ownership of managing things I had previously ignored or took for granted felt like I was honoring that purpose...and that made me happier/more satisfied.]
And, I told my kids they can't count on things being as nice as they were for me. Things might be that nice, and if they are, great, but they shouldn't count on it. I told them that my generation is borrowing from their generation at WWII levels even though there is no WWII going on. So, I think they are taking their college seriously...only pursuing degrees that are marketable, so that they can be less miserable and have fewer "fragilities" to worry about.
Bottom line: I can only do what I can do...and I decided to actually do it. I don't worry about what I can't do.
