If you don't believe in your own greatness, you will never truly pour all of yourself into your craft, and all of you is required to manifest the abundance that is present.
Self doubt will distort your assessment of what you produce, and drag you down into the darkness of comparison and resentment.
Take the time to cultivate a deep appreciation for your ability, your work and the potential for impact. The alignment of love and gratitude is the key to the flow state, and the flow state is the portal to your highest self.
