In my own professional experience, just like it says on the Lululemon bags, being jealous or competitive does the exact thing you are afraid of. It will stop opportunities from coming your way and as we all know, it feels terrible.
Again, speaking from my own experience, 100% of the time, when you support your friends abundantly in business and they do the same for you (even if they are direct competition), you will create so much opportunity that you will have to give business away. Sounds a little crazy at first, but it's so true.
In this quick video, Marie Forleo reminds us that there is plenty for everyone. And also, to keep rising up... "there is nothing enlightened about shrinking so that other people won't feel insecure around you." via Marianne Williamson (so right).
