Today marks exactly five years of daily Close-Up pictures of my face. Close-Up is a little app without flashy features that allows you to simply snap a selfie each day and stitch them into movies highlighting your your physical deterioration.

It might sound stupid but I’m a bit proud of this. Doing something daily for five years, even if it’s just taking 5 seconds to snap a quick selfie, is not as easy as it sounds. There’s a metaphor in here somewhere for how incremental work creates exponential results.
