@Mrfunkedude It's about balance. Fear of nuclear winter? There's little you or I can do to stop that, so that fear is indeed a waste of time. Fear of becoming disabled in a capitalist society? That's a very real thing that happens to everyone on a long enough timescale. That fear can motivate us to properly prepare for that inevitability.
If the fear is rational, address it, make a reasonable plan, & move on. If irrational, push it aside & live life.
I'm still learning this.
