Being able to properly convey information is a skill very select individuals master. It's usually something that has to be learned through experience rather than taught by instruction.

Experimenting and practicing help a lot in the learning process. It's impressive to see this at work, when students who didn't understand a thing from theory, have their aha moment when they experiment.

Advice can help but explaining the process is a key component to being able to teach.

I agree, but that sounds easy, and it's not, to explain a process to the level of the person you speak with. Try explaining Hive to someone in 2-3 minutes in a way that is attractive to them!
