It's not who you are that holds you back, it's who you think you're not- Anonymous (a re-post from Pushy Dreamers)
Shhh, did you hear that?...there is goes again..that voice in your head that says, "Who do you think you are", "You're not all that". I encourage you to stop listening.
Listening to the voices in your mind leads to spiritual death. When you don't show up everyday in the fullness of who you are and stretch yourself toward your highest potential you might as well not be living. Life is waiting for you to live it in it's fullest capacity, to break the molds and recreate what is possible.
Feel the fear of being your best self and move forward. Marianne Williamson said it best in her poem Our Deepest Fears, " ...Your playing small does not serve the world. There is nothing enlightening about shrinking so that other people won't feel insecure around you. We are all meant to shine..".
Are you shining? Are you living the life that you imagine for yourself? If not re-evaluate what is blocking you. Stop shrinking and start shining.
