Practice practice practice. More obviously, you can't type faster than you can think. Take the effort to prepare your thoughts. Develop a flow for your stream of consciousness. Typing on the fly requires a kind of cadence and rhythm that only comes with developing a proper form. Honestly best advice is just get a keyboard you're comfortable with. I'm quite fond of my WASD keyboard. The sticky keys on my MacBook Pro just don't cut it. I learned through doing runs of Mario Teaches Typing so fast that the computer struggled to render frames. My typing speed's gone down, substantially over the years. I think that's a good thing. I think slower. I pause before I speak. I try to say more with less words. I've also picked up a weird habit of using only my index finger for my right hand but my WPM is still around 100.
