I also have a very, "The world's gonna do what the world's gonna do, the best I can do is find my path through and flow with it," attitude about, well... most things. Maybe that helps? Maybe I'm talking out of my ass rn? I'm unsure! :)
Few people have anything that comes anywhere near any sort of philosophical foundation that they can rely on to weather their anxieties. If anything they only strengthen their sensibility to express—and compound—their worries.
I don't know what's going to happen. Maybe I'll need to figure out childcare, maybe I won't. Maybe I'll have food to eat this weekend, maybe I won't. Maybe my job will go away next year, maybe it won't. Today, there's work, and I'll do that work as best I can. Today, there's evidence things are changing, and I can be aware of that. Today, I can do something prudent to make myself more resilient towards whatever may or may not happen. Tomorrow, if something happens, I can react accordingly.
The mind wants certainty, but that's not always available, so I observe the "wanting". The best I can do is act based on what's in front of me, and sitting in the negative emotions around existential thoughts doesn't help me, nor my family (it's natural to have them, but I acknowledge them and let them pass by). The best I can do is to do. If things change, I change. Everything in nature/life is ephemeral, and I have done my best throughout my life to set myself up to be as adaptable as possible.
Edit: To reduce this and get a bit Tao-ish, you don't need to know the exact shape of the river downstream as long as you're capable of steering when you get there.
I take it you've never worked on realtime software. :)
For most Americans with kids, if they don't figure out childcare they will miss deadlines. By missing deadlines they risk systemic failures: failure to make enough income to eat, keep their job, pay for healthcare, etc.
It's easy to get Tao-ish about meeting deadlines when your buffer is above 100k.
That's not to say that things aren't easier or harder at different levels, but you can still approach life from that perspective no matter where you are at. I've always lived a life far from the the income levels that are common around these parts, and this is how I've to sustained myself and remained happy.
