Take a picture every day of the year, become a better photographer and never forget a day in your life.
Here's a brief description from PhotoJoJo.com:
Project 365: How to Take a Photo a Day and See Your Life in a Whole New Way
Why do it?
Imagine being able to look back at any day of your year and recall what you did, who you met, what you learned… (Often we find it hard to remember what we did just yesterday or even last night, let alone a whole year ago!)
This application will allow you to easily create and update your own project 365 photo album. To add new photos use your iphone's built in camera or choose from your photo album. You can share your photos using facebook, twitter or email.
