Definiteness of purpose is the starting point of all achievement. Life isn't about getting and having, it's about giving and being. You take your life in your own hands, and what happens? A terrible thing, no one to blame. A person who never made a mistake never tried anything new. Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it. The only way to do great work is to love what you do. I have learned over the years that when one's mind is made up, this diminishes fear.
Believe you can and you're halfway there. Dream big and dare to fail. Build your own dreams, or someone else will hire you to build theirs. Eighty percent of success is showing up. You can't fall if you don't climb. But there's no joy in living your whole life on the ground.
