Sparks are extremely fragile things. These "sparks of madness" come from the giant fireball of creativity. WHEN this spark lands on you, take care. This spark may hurt a little--it's fire, after all--but that can't deride you from your dreams. If you take off when your park comes, it will go out without your nourishment. When this tiny flame hits you, don't douse it in water! Your creativity will go with it.
We're surrounded by people who have lost their sparks over time. Don't be one of those people! You must raise your spark. Be fun! Don't let excitement come to you, it might not come! Go find those opportunities, and get your dream. Find your spark!
Then, when you have the spark, keep it. Work on it. Raise it to a roaring fire. Once your flame is great, you will be too.
Your spark is out there, and so are you.
