I got a better keyboard. I had some bad typing habits that a regular keyboard was "allowing". I tended to reach across the keyboard with my dominant hand and left my non-dominant one to easily accessible keys. Needless to say, typing was slow and error prone.

Then I tried one of those keyboards that splits in the middle. It forced me to break my bad typing habits, I literally couldn't reach across the keyboard anymore, it was waaayy to far to move. My WPM went from 30 to 60 in about two weeks. (Microsoft Ergonomic Keyboard 4000, for those interested. About $40 on Amazon)

Typing faster allowed me to express my ideas much quicker. I could iterate faster, solve problems quicker, etc. etc. I started moving around the computer with my mouse less, so common operations like saving and opening files sped up.
