Don't waste your life in doubts and fears: Spend yourself on the work before you, well assured that the right performance of this hour's duties will be the best preparation for the hours or ages that follow it.

Success in business requires training and discipline and hard work. But if you’re not frightened by these things, the opportunities are just as great today as they ever were.

Only those who dare to fail greatly can ever achieve greatly.

To be successful, you have to have your heart in your business, and your business in your heart.

If you cannot do great things, do small things in a great way.
