Ok, so unicorns aren't real. (Yet? Hmmm...)
Not too long ago, neither were cellphones, computers, airplanes, or any of the modern and technological conveniences we take for granted.
Creativity usually starts with a question, 'What if...."
A good dose of belief helps propel and fuel the process.
If you set off with curiosity and belief in yourself, then the blank page begins and becomes. And, the opposite is also true, if you believe you will ruin the blank page, you probably will.
The same holds with any creative process. Once the idea and intention is set, it's belief that drives gathering the right team and resources to test, develop, and eventually create your product, whatever it is. Once the belief turns to "it can't be done," then it won't be, because all effort will stop.
When you believe with your whole being, you harness the creative power of belief. Do you want to create health? It's most important to believe you will be well. The placebo effect has been well proven, as has the power of belief in healing. Yes, you might need medical help or therapy, but with belief and time, you can choose positive thought patterns and habits to contribute to creating your healthiest self.
What do you believe is worth creating in your life?
