Although I did chose a degree (not necessarily the best one), I bounced around after college. Temped for four years in all sorts of departments (financial, communications, engineering, R&D, wellness). Loved it. I eventually "fell" into a career. My Aspie-like BFF got a Masters and then worked minimum waged jobs for near 10 years before she "fell" into her career. Maybe there was a "better" way, but it worked well enough. Now we are both in our late 40s and wanting to do something different... so back at square 1 (for me, she wants to continue in her industry).
So, I'm right there with you again: scared of the future. And I would look forward to my future 60-year-old self looking back on my current 40-year-old self and thinking: it all worked out just fine.
