The bigger problem is that there's often no one willing to show you how to use it. I had a friend who managed to picked it up himself, and when I asked him to show me the ropes all I got out of him was "just Google it". Now, of course that's how you figure all sorts of things out and an essential skill in itself, but first you need to know what to search for, and if you're just starting out you're probably not going to know what that is - or you'll have more abstract but simple problems like figuring out issues with syntax in the terminal. That kind of thing is really easy for another person who knows to say "no, it's like this, because of that" but can be very difficult for a person to figure out on their own.

Quite often it seems like people have gone through these trials themselves, but then rather than making it easier for other people and helping them they leave them to face the same challenges all over again from scratch. This is very frustrating, when you know there's an answer that someone could just give you but it's not apparent to you, which leads to people throwing in the towel.
