Risk
Say it like this
The chance that the thing you hoped for does not happen.
For the grown-up
Risk is the possibility of an outcome worse than the one you planned for. Everything worth doing has some. The useful skill is not avoiding risk but knowing roughly how much you are taking and whether you could survive it going badly.
The easy mistake
Careful here. A risk that pays off was still a risk. Children, and adults, reliably judge decisions by how they turned out rather than by what was known at the time.
