One of the most exciting times in the life of any business is in the early days. You scrape together enough cash to pay a few employees, fund the operation on your own, and push hard to make it a viable entity. These entrepreneurs and experts know all about perseverance. They have lived through the financial hardships of starting a company or riding out a business challenge until they achieved success. You can do the same.

6. "No matter what your reason for wanting to start your own business, developing the foundation is the same. Laying a solid foundation for your business will provide you with a road map to follow as you build your business.

Estes, author of Start a Business Step-by-Step Workbook

10. "In order to be a success in business, there is one thing you must do. You cannot be successful without it. That is work. I have not told you anything new. Everyone knows that you cannot be successful in anything without work. Why doesn't everyone work? Because some lack the one thing that makes men want to work: enthusiasm. That is something no one can give you. You must acquire it yourself, and the only way that you can become enthusiastic about anything is to have a thorough knowledge of it. You have never seen an enthusiastic man who was lazy." --Thomas J. Watson, CEO of IBM

44. "It's hard to tell with these internet startups if they're really interested in building companies or if they're just interested in the money. I can tell you, though: If they don't really want to build a company, they won't luck into it. That's because it's so hard that if you don't have a passion, you'll give up." --Steve Jobs, co-founder of Apple

45. "I love what the Valley does. I love company building. I love startups. I love technology companies. I love new technology. I love this process of invention.
