I write using Dragon software, which I find more accurate than Google voice recognition, and a Bluetooth headset. Not only does this spare my wrists, but it frees me from my desk. I can walk on a treadmill, load the dishwasher or do laundry while I work. Sometimes, I’ll even write on a long drive.
It takes some getting used to at first. But the productivity increase is well worth both the money and the learning curve. I recommend it to everyone who writes a lot.
