One of my most difficult technology problems was when I was taking Data Structures and Algorithms and having to learn C++. My professor at the time had just came from working at Google and let go of how he thought the class before. He did not provide us with a text book and threw a bunch a C++ code at us the first day of class. But in that class I struggled with Binary trees with deletion and insertion but was able to finish my lab because I started asking questions. I struggled only with that class because I didn't ask questions.
