“A Muggle security expert would have called it fence-post security, like building a fence-post over a hundred metres high in the middle of the desert. Only a very obliging attacker would try to climb the fence-post. Anyone sensible would just walk around the fence-post, and making the fence-post even higher wouldn’t stop that.” —HPMOR, Ch. 115

Have you tried whiteboarding-related techniques?
I think that suddenly starting to using written media (even journals), in an environment without much or any guidance, is like pressing too hard on the gas; you’re gaining incredible power and going from zero to one on things faster than you ever have before.
Depending on their environment and what they’re interested in starting out, some people might learn (or be shown) how to steer quickly, whereas others might accumulate/scaffold really lopsided optimization power and crash and burn (e.g. getting involved in tons of stuff at once that upon reflection was way too much for someone just starting out).
