Why do you write? Why do you rhyme? Why do you paint or draw? Why do you build?
Most people want to see the world a better place. We might not always see eye-to-eye on how to do that in a holistic sense, but one thing that spurs on the creatives and artists is a desire to make the world a little more beautiful. Some simply want to entertain. Some wish to inspire. Others long to provoke thought or create change. Others create for different reasons or combine reasons together.
Your imagination is a gift.
However you decide to put it to use, use it well. Let it soar. Inspire, encourage, entertain.
