My thirty days challenge started on Friday. I chose to take five pictures a day, and it went well for the first three days. On Friday, I took a picture of my lunch at dinning hall, a little white flower near the road, tiny slippers of my roommate, my Cheshire coffee cup, and the moment when my friend turned around. I saved my photos in the camera and left them. This morning, i was quite excited when I looked my them. They helped my recalled my life a few days ago. I could remember the every minute behind those colorful and vivid pictures. Then, I realized that the true power of photography exists in its eternal probability of lasting. If I form it as my own habit in this thirty days, maybe after ten years I would be surprised by how time passes and the every moments I keep in the computer or the frame. For now, taking five photos is not a heavy job. However, I guess maybe after two weeks I might be annoyed about finding elements. All in all, no matter what, I will not give up on this, because I enjoy sinking into my world of photos and memories.
