Creativity is an excess of personal energy. What to do, oh what to do with it? The best use of this energy is when it's organized into meaningful constructs.
If you have too much energy and no outlet, just possibly you might need to create something, and soon.
Focus the energy into solid form of your choice. Use your hands, your mind, your ability to feel and interpret. That depressed empty feeling will go away really fast. Sure it's a temporary solution, but isn't time all we've got anyway?
Fill your time up with something that generates wonder.
