According to the authors of "How to Think Like Leonardo Da Vinci," the first step is to be curious. So, just curious. What are you curious about? And beyond curiousity, what do you yearn to know?
Do this. Ask a question you have never asked before. Write it. Explore it. Journal it. Don't worry about answering the question, just focus on the asking. A well-asked question has incredible power.
It'll make a genius out of you.
