Never consider the possibility of failure; as long as you persist, you will be successful.

Self-discipline is the key to personal greatness. It is the magic quality that opens all doors for you, and makes everything else possible. With self-discipline, the average person can rise as far and as fast as his talents and intelligence can take him. But without self-discipline, a person with every blessing of background, education and opportunity will seldom rise above mediocrity.

Successful people tend to become more successful because they are always thinking about their successes.

Keep asking yourself, 'What kind of a company would my company be if everyone in it was just like me?'

Persistence is self-discipline in action.

Practice is the price of mastery. Whatever you practice over and over again becomes a new habit of thought and performance.

Your outer world of attitudes, wealth, work, relationships and health will always be a reflection of your inner attitudes of mind.
