I like stories. But I tend to like stats more. Stats are stories in form of numbers. And I subscribe to the whole "What gets measured gets improved" idea.
The tools I mainly use are Goodreads, Strava and Trakt. Then all data come together in my own little neat spreadsheet.
Here's some of the things I've been tracking. I log my runs and the books I've read, for improvement. Others, like movies watched, for fun.
