I struggle with this toppics, On the one hand I do think that we shpuld be positive and focus on good outcomes in every situation

But on the other hand, too much of "positive thinking" can (and will) make us naïve for the worst outcomes.

Granted, you don't go talking lightly about this things with people you don't have an inmense amount of confidence with, but I also fear that avoiding to think abput potencial catastrophic outcomes takes away the chance we have to change those potential outcomes when we still can.
