Readers who
don't stop.
I finished three books last month. I haven't done that since university. The speed just creeps up on you — one week you're at 300 wpm, the next you're pushing 600.
I was sceptical. I thought I'd miss the experience of reading normally. I don't. If anything I'm more absorbed because there's no scanning, no losing my place.
The gift feature is what got me in. A friend sent me Meditations and I thought — okay, I'll try it. Two days later I'd finished it and downloaded four more.
I commute 45 minutes each way. OneWord turned that dead time into the most productive part of my day. I've read more in two months than the previous two years.
The streak feature got me. I'm not competitive by nature but missing a day felt wrong. 47 days in now.
I sent Think and Grow Rich to my whole team. Half of them downloaded the app within the week. We have a group chat now about what we're reading.
