Agreed. I have another bone to pick with this article as well.

"X is bad. You must do Y to succeed."

Absolute statements like this are almost always dangerous to make, and I don't trust the articles that make them. Success or failure at anything is all about making the right tradeoffs. Advice should focus on helping you weigh those tradeoffs intelligently rather than dictating absolutes.

But dictating absolutes is so much easier, and I guess that's why everyone does it.
