For me the key to enjoying abundance was to realize that abundance has nothing to do with money. It has to do with our ability to share our creativity with others.
When I realized I could enjoy this type of abundance no matter what, I was able to let go of my fear of being broke, homeless, financially destitute, etc.
This level of awareness started opening up to me when I was sitting on the beach, looking out at the ocean and realizing that this beautiful scene in front of me was free and could be enjoyed at any time. I realized that even while I was broke, I could still enjoy the beauty of nature, and I could still live a worthwhile life. I'd been giving my power to money, but I could just as easily choose to stop doing that. This taught me to hold onto my power, peace, and happiness regardless of circumstances.
If you think abundance = money, you'll never experience true abundance because you're casting it outside of yourself. Abundance is something you can start experiencing while you're totally broke or deep in debt. Of course once you get there on the inside, your external reality will transform as well. Just give it a few months or years to catch up.
