Why are Excel shortcut myths dangerous?
Why, you ask? Because Excel is the most popular business software ever in the world (hundreds of millions of users), and probably the most important. If you are in the business world, you need to know Excel, and the faster you can be at Excel (e.g., with shortcuts), the faster your business (or your part of it) will run. The faster you and your business can run, the more successful you will be. This means: promotions, pay increases and greater job satisfaction. Being fast at Excel makes you more valuable as employee, which increases your upward mobility on the pay scale. All kinds of new possibilities are opened up for such magnificent people.
If you decide to put off learning shortcuts, then you are putting off advancing your career. Therefore, any myths and misconceptions that keep you from learning shortcuts are dangerous to your career. Multiply this by several hundred million people and you’re hindering the global economy!!! You are in fact decreasing the total amount of cosmic happiness!!! These myths are dangerous indeed! They are nearly as dangerous and misguided as the ancient practice of bloodletting (see below). Bloodletting is as smart as avoiding Excel shortcuts. See, these evil men below are simultaneously bleeding the naked guy in the chair and telling him Excel shortcuts are bad for his health.
