I don't really sort my photos. I just take them, download them and keep them. I've got a big hard drive, so what?
Each blurry, ill-thought-out shot makes a little mind picture of what the day was like. I've now got around 150Gb of photos and videos. All of which I find a little bit precious. Especially when they stretch back to before I was born.
Here is me today. I am studying my PhD.
Here is me twelve years ago. I am dancing to music.
Here is me seventeen years ago. I am learnding.
Here is me twenty-eight years ago. I am SAVING THE WORLD.
