I totally agree with you both. People seem to expect a recipe.. But forget that even there it's expected to how to use scales and volume measurements.
tl;dr; some experiences from my real job:
Hmmh, children usually have more intrinsic motivation to explore and learn new things compared to adults and are far more resilient in case of obstacles. (Just think about the whole process of learning to walk.)
Yeah, the toddlers, throwing on the floor having a tantrum at the supermarket, that's different. That's more an indication of developing a self-personality and voicing needs and feelings.
Imo it's a more of a typical adolescent/ early adulthood behaviour to have a low frustration tolerence if things don't work like they expect or desire them (aka that the whole world doesn't revolve around them).
@Tionisla @joel Interesting comparison, and quite appropriate. Thank you for sharing it!
