Nobody is in Your Head
Humans are unique in that we have the capacity to self-talk (animals do not as far as we know). We process, analyze, over analyze, strategize, think, ponder, wonder, guess, second guess, synthesize all without ever actually doing anything. Many times greatest fears often shape our thoughts. The fear of the unknown or the fear of failure creeps in to paralyze us into action. Your thoughts, good or bad are only ever in your head, that is until you express them to others, which is where the magic happens. The magic is not in mind reading.
Your customers/clients/vendors/partners do not know what is in your head. They do not know what your dreams and aspirations are. They don't know why you got into the businesses you got into. They don't know anything about you. How could they if you never told your story? If you want people to understand your message, your purpose, your passion, then you need to put that into the universe by expressing it. Make a song, write a mission statement, record a video, do something that crystalizes who you are and what you are about. This may not ever get you out of your head, but it will add clarity as to what is inside of your head and heart.
We connect with humans on an emotional level. If I can understand you, your brand, your message, then I can choose to connect with you. If I can't understand you I'll most likely give my attention to another person/brand that is telling a story worthy of my attention.
Remember, nobody is in your head, until you invite them in.
