From guessing to knowing: my sleep tracker story

I used to just assume I was getting enough sleep every night. A couple of years ago, I decided to try a basic sleep tracking device. It showed me that I was actually waking up multiple times without even noticing. I started cutting off caffeine earlier in the day, and my sleep quality improved. It's funny how a simple gadget can make you aware of habits you didn't know you had. Looking back, these tools have gotten so much more detailed than the old clip-on pedometers. They're not magic, but they sure help you figure things out.
