Day 3 Colemak

Well, I'm typing this in Colemak, which is something. In day 1 I just learned the keyboard layout and maxed at about 10 WPM. Day 2 I moved to typeracer and maxed at 16 WPM. Today when I woke up I hit 21 WPM. I can start to feel my muscle memory developing for some common words, but it's spotty at best. The S key in particular really throws me off. Overall it seems like common words are too easy to type and should be harder, damn you QWERTY.
