One of the key differences between a professional and a nonprofessional is that a professional works just as well without internet access as with it. A professional doesn’t need Google, a tutorial, or a reference manual. The first sign of a nonprofessional is the phrase: “Everything is on the internet.” A professional knows that there’s nothing on the internet and that you can rely only on your own knowledge and your own experience.
A very simple experiment: turn off the router in the office. You’ll hear the first shouts after just 5 seconds — that’ll be the juniors yelling — they’re blocked without the internet and can’t do anything. A professional will find out there’s no internet only an hour later, when he comes to the kitchen for a cup of coffee.
