There was a day that someone looked up at the moon and said I wonder if I could ever walk on that...and they made it happen!! Your mission must be greater than your fear & doubt! Don't limit yourself with what you "feel" is impossible. Feel the fear and do it anyway.
Get out of your comfort zone and Go and Conquer your day!
