When do I feel most creative?

Creativity for me is a constant. No certain time of the day, month, or year holds my most creative time.  I can honestly say I am most creative when I am sparked with an idea and a bit of a challenge.  You add a bit of problem solving into a project for me and I will attack it like a school of piranha and the ideas will flow out of me like the sprays of water from the piranha tales lashing in the water.
