"Time is money." —someone [who charges by the hour].
What a lie we've been taught.
Not because it takes longer it's better —or even well done.
Here's a thing for you to think: Does more time equal greater impact?
The more you specialize, the less time it takes. The more you see the patterns, the more efficient at identifying the root problem you get. Also, the more you see the trends, the most Inefficient you'll get (because you'll tend to innovate).
