Headache before Aspirin

To get the most out of this training, you must follow a golden rule: wait until you have the headache, before reaching for the aspirin.

In practice, this means avoiding clicking on tempting links, such as those listed in the "Useful links" section of each exercise, until you really need them.

It's easy to get stuck in a rabbit hole when learning to program, and every article you read leads to every other article – it's overwhelming. For this training, avoid following the rabbit hole. There's zero credit for extra reading. In fact, there's extra credit, the less reading you do – unless you really need it.
