Fully agreed. I was like this (overthinking what if’s) for many years, and the amount on energy spent on this left me spent to actually go and live in reality. The upside was having a plan for nearly whatever life threw at me - but discarding hundreds of alternate plans. Now as I grew older I have learnt to be much looser with life steering, as we are not in full control anyway. Just have a general direction of what you want to do, and spend the rest of your energy here and now...
