Why can't you learn data structures from a book in a coffee shop? I did.
I would argue that you can't learn the theory until you have enough practical experience to actually implement and play with the theoretical concepts you are learning about. By not learning "the trivial stuff you can learn from an Oreilly book in a coffee shop", you are wasting your on time. The sooner you stop wasting your own time, the less of it you will waste.
