I often hear people say that they want to start their own business, pursue a dream, follow their passion. If you want to start a business, you don't need a degree, venture capital, loans, business plan or other "essentials" that often become distractions and excuses. So what's really the problem?
Far more than anything else, fear is the main obstacle that holds us back. So instead of pretending to be fearless, while buckling beneath the surface, learn to work it. Believe me it will never go away, but you can avoid letting fear make decisions for you.
