Still Hunting for Keys on Your Keyboard?

Real skill acquisition requires practice. And if you work on a computer, your practice almost always involves typing!

Believe me — as someone who switched from "hunt-and-peck" typing where you're constantly distracted, glancing at the keyboard, with attention continuously fragmenting, and a low typing speed ceiling (which impacts productivity overall)...

Our brains naturally take the path of least resistance, leading us to adopt incorrect techniques (whether it's keyboard typing or hand positioning when playing a musical instrument). This becomes both a narrow comfort zone and a limitation — sometimes even causing health issues!

If you work on a computer and type frequently (coding, for instance) — don't procrastinate. Start your transition to touch typing. It's a worthwhile investment!

I built a dedicated application for this: FingerGo.
