“Just” makes me feel like an idiot. “Just” presumes I come from a specific background, studied certain courses in university, am fluent in certain technologies, and have read all the right books, articles, and resources. “Just” is a dangerous word.
“Just” assume that the other person knows what you know. But you know what you know from experience, education and previous jobs. The person you’re talking to might not. Try to remember this the next time to explain something to someone.
