I love The Journal. It's the perfect tool for a writer. Not only does it keep your daily journal, it's also an information database.
The program is extremely powerful, with a mass of features. I've used The Journal for years, but I keep discovering new ways to use it.
For example: my writing log. Because I track my work (otherwise I get to the end of the day and can't remember how I filled it) I like to keep a spreadsheet work-log open as I work. Instead of opening a spreadsheet program, I've found that I can create a Work Log template, with a table in it, in The Journal. Each day I use the Insert Template feature, and a fresh work log is entered into that day's notes.
Try The Journal.
(Disclosure: I have no financial interest in the program, I'm just a very happy and satisfied user.)
