Today, I declare, is the day of occurrences of interest. For instance a mysterious cave, unexplored attic, or locked door. Or take a smallish highway and see where it goes. Who could resist? Another idea is the impromptu half-remembered party, at which shattering secrets are accidently disclosed in a blurry alcoholic conversation on the back steps. Don't like those? Try this on for size: Shaken from complacency by a brush with catastrophe. Doesn't food taste better? And the sex!
Any of these would do. If you decide to get out of bed in the first place then something might as well happen.
