I have been pretty faithful about posting one photo a day for my 365 Flickr project. Yesterday was the 100th day. I have missed one or two days, but some days I post more than one photo because I can't choose just one! Nearly every photo was taken with my phone. I always have my phone with me, and uploading the photos I take with it to Flickr is as simple as hitting the share button, so I haven't run out of steam yet.
This project has perhaps made my photostream a bit dull to an outsider, but for me, I like looking back and seeing what was worth remembering that day.
