I'm scared
This isn't the first time in my life I've closed the door behind me, leaving everything to start from scratch somewhere else. But in those instances, I was moving within my own country or culture, I knew I had a family home to return to if necessary, and, above all, I was young enough to start over.
Now I'm 53. I have a plan, and I'm not crazy... but still. If something goes wrong and I'm already 60 or 70, stuck who knows where, I could be in serious trouble with little room to recover. So, while I know what I want and have no hesitation, even with the best decisions on my side, things could go terribly wrong. I'm scared.
However, there's only one reason I'm scared: because I can be. I still have human emotions; I care about myself. I'm not a ghost yet, just a work in progress. I identify the flaw, and I'll work to fix it.
I'm still scared, but that won't stop me. I have a goal, and I'm on my way.
