The time is now!

You'll strike upon an idea too exciting not to act on immediately.

Hooray! I'm hoping it happens soon because the only ideas I've had so far today are

Go Back to Bed
Fill out School Paperwork
Clean the House
Go to the Pool

And, while Go to the Pool isn't bad, I've already had that idea (and acted on it) several times this summer and I wouldn't exactly describe it as "exciting."
