This doesn't seem like a difficult question and yet, it is.
Before you decide how to say something, whether it's marketing an idea or a writing project, you first have to know what it is you want to say.
So how do you figure out this piece of your creative process? How do you find your voice?
Start talking.
Face it, many of us don't allow ourselves to say what we really want to say. We hold back, bite our tongues (literally or figuratively). Or we repeat what we think should be said.
This is your opportunity to vocalize your idea(s), to express your authentic self - no matter how crazy it may seem. You might be surprised by what emerges when you remove your filters.
You'll know when you've found the right words because when you say them out loud, they will feel right. (Or scare you, it could go either way).
No matter what your reaction, you'll discover the most important element of your creativity - your voice.
