First things first. If you want to make a difference in the world, you have to start with yourself.
As above, so below. On earth as it is in heaven.
The patterns of relating that you set up in yourself play out in your relationships, your family, your career, and the world at large. And that makes self-love the most effective revolutionary action you can take. Accepting yourself as you are is the essential groundwork for relating to others with empathy and compassion. And that's the movement we need to build a more beautiful world. Ultimately, if you're hard on yourself, you won't be easy on others. Even if you are sweet and sympathetic outwardly, you'll harbor bitterness and resentment in your heart, and this energy will run the show from the shadows, causing dissonance and frustrating your creative efforts.
But drag that stuff out into the light and look it in the eye. Admit it, you can sometimes be your own worst enemy. From that admission, you can forgive yourself, start to heal, and move on in wholeness. And doing that for yourself will set up the basic pattern for what you can offer to those you love, and those you work with, and that healing ripples out into the world in a profound and beautiful way.
The first step in making any change in the world is changing yourself. Get clear about your values and start living them from the inside out. You'll be amazed at how much support you'll get from the universe when you come into alignment with yourself.
