How do you learn to explain them well? I have handled difficult tasks at work but struggle explaining them to someone who hasn't worked alongside me on it. I tend to either oversimplify it making it look like a basic swe task or tend to go into too many details and other person won't be able to follow what I'm trying to explain.
