The other half of it is learning to engage more with other people's code and get inside their head. The stereotype of the young coder, when given no oversight, is to skim over something, declare it crap, and start rewriting without even trying to maintain the original. Sometimes that is the correct move, but since they haven't engaged with long-term maintenance before, they can't tell the difference.
