Hey, no excuses! Here's a great little web app that allows you to set goals, and track your achievement (nothing fancy, just a check). If you have multiple goals, it gives you a total score for the day.
You can track, as an example "Did I walk the dog", "Did I walk the dog again", "Did I take the dog to agility", "Did I give very good dogs extra cookies". Stuff like that.
And it has a cool graph that you can add to your blog.

We also really really love that it is written in ColdFusion
