I like to track how many Big Ideas I have. (Technically I call them Big Ass Ideas - I'm not sure why, other than I like the sound of it. Not everyone likes that thought, so I abbreviate it BAI).
I track it, because what gets measured gets done.
The impact of a BAI can be huge - even if a particular idea never gets made into a new process (I also track new processes).
Since I track the ideas I also set aside time to generate the ideas (it doesn't always happen during that time, but it's a good practice). Occasionally when I go for a run I leave the headphones in the gym bag. I leave my mind open to ideas. It might happen on the run, or I might just wind up listening to the birds and nature. Neither of those is a bad thing. Frequently it will happen after the run. The ideas that have been percolating will come out when I get back to my desk.
Occasionally the impact goes well beyond the big idea. Today I was tired and dragging when I got out of bed. When I got to the point in my morning routine where I reviewed the upcoming day I saw that I get to implement my new big idea - the Top 4 projects categorization tool (more on that tomorrow). Suddenly I'm fired up and can't wait to start the day.
