Seek Experts

Experts have the knowledge you seek. Keep in mind, experts aren't necessarily good teachers. If possible find experts who are good teachers. Otherwise, it's up to you to figure out a way to extract knowledge from the expert. (See You Are Your Primary Teacher )

Sometimes an expert will say something like, "There are no stupid questions." Which means they don't remember what it's like not to know what they know and they need you to ask a question so that they can remember what they know and tell you what you need to know. The experts aren't trying to withhold information, they just haven't thought about what things you need to know. So be curious and ask questions.
