The most annoying thing when learning to program is that experienced programmers take your bullet points for granted -- and don't explain them well / don't explain them at all. But grokking those bullet points has a significant material impact on your ability to pick up the actual language itself later on.

The same is true when you're experienced -- programmers often say that programming is easy, which is because _syntax_ is often easy. It's the mechanics of how everything fits together that is difficult, and is often overlooked as a concept.
