Now, I am not a qualified statistician or mathematician or anything like that, but sometimes it's fun to track the trends and what lot of all this work you put in while trying to make positive changes in your life.
In that regard, I spent a little time (weeeell...justthewholedaynobiggie) crafting a little dashboard/weight tracker for myself. I did the added bonus of a very non-glamorous update to my desktop. Just some text and numbers, since it's on my work computer and anyone could come across it at any time.
Some pics:

That's the big one, the Year to Date tracker. I love it <3. I also made one for monthly updates, and I'm a fan of that, too.

That's my quick and easy little desktop reminder, to be refreshed weekly.
What do you like to track? This is one of many of my goal check-in systems. How do you track your progress against your goals? I'm guessing it probably isn't as nerdy Excel driven as me, but I'd still love to learn about some other techniques!
