One thing I've noticed, though, is that I am often too lazy to write every day, no matter how much I want to. I have tried and am still trying different ways of outsmarting myself, such as leaving the journal on my pillow so I have to consciously set it aside before bed. Nonetheless, I occasionally find myself behind by a week or more.
While I still plan to write every day, as one of my goals of doing more software development for fun, I coded up a hastily-written, hastily-named, lightweight application and put it up on GitHub: Journal Today, which lets you write daily notes about... whatever.
The first version exe can be found here:
Update: JournalToday_20150227.zip (373kb) now uses DateTimes internally for better date calculations.
