Ask why when you:
- feel unmotivated to work on a task
- feel like you’re a order-taking robot
- iterating more than twice on a design
- told to do something that doesn’t have the work ‘because’ in it
- client asks to do something and tells you what to use
- spent an hour to solve a problem that you estimated to take 10 minutes.
- do what you’re doing now, just to remind yourself of the purpose
