I always thought one year is a fairly long amount of time, but then I tried to draw each day of the year as a square in a grid.
Visualizing each day in a year put things into perspective and made it clearer how valuable is each moment we spend.
To put some content in the aforementioned visualization, I started tracking a collection of things that I could do on an average day. I thought it would have been interesting, once one year of data has been collected, to take a look at the whole picture trying to recognize patterns.
The project started on 04/23/2016 and will end one year from that date, on 04/22/2017. During this period I will use a custom little Android app to keep track of things that I do every day. The app posts each thing that I mark as done to an HTTP API written in Go and running on Google App Engine.
