" Don't fear big. Fear mediocrity. Fear waste. Fear the lack of living to your fullest. When we fear big, we either consciously or subconsciously work against it. We either run toward lesser outcomes and opportunities or we simply run away from the big ones. If courage isn't the absence of fear, but moving past it, then thinking big isn't the absence of doubts, but moving past them. Only living big will let you experience your true life and work potential. "
