“If you believe in what you are doing, then let nothing hold you up in your life or work. Much of the best work of the world has been done against seeming impossibilities. The thing is to get the work done.” -Dale Carnegie
As many others before me have written, you need to believe in yourself before others can believe in you. When you believe you can move a mountain, you can move a mountain, one stone at a time. All it takes is a dream and some persistence.
