Putting myself into categories is fun, and I think it also gives me insight into my own nature. When I see myself more clearly, I can more easily see ways that I might do things differently, to make myself happier. Categories can be unhelpful, however, when they become too all-defining, or when they become an excuse.

I've always loved 'Before and After' stories, in books, magazines, and TV shows. Whenever I read those words, I'm hooked. The thought of a transformation - any kind of transformation - thrills me. And that's the promise of habits.

Don't let yourself fall into 'empty.' Keep cash in the house. Keep gas in your tank. Keep an extra roll of toilet paper squirreled away. Keep your phone charged.
