Being average is okay. Mediocrity is tolerable. But what are you doing to go above and beyond the call of duty? What are you doing to make yourself stand out in a positive light, or to make the lives of those around you easier? If nobody ventured out into new and exciting things or ideas, nothing would ever change. The world would continue to exist with nothing improved. The great thinkers and dreamers throughout history strived for excellence, strived for ways to change the earth. So attempt grand things. Dream your dreams, and then live them out. Expect a lot out of life.
