Too often people discount their accomplishments and focus on what they haven't been able to do. Making money in itself is not success, but rather a by-product of success. Most successful people use the technique of visual- isation to foresee ideal outcomes. As a man thinketh so is he. Success or failure is not a matter of luck.
All successful people have true grit and stickability, as well as natural ability.
The winner is often the person who gets up one more time than they are knocked down. You will hit attitudes in others who say 'you can't do it'. All the world's greats would never have been great if they had listened to the opinion of even their closest friends. Thomas Edison, the inventor of motion pictures, was advised that no-one would pay to listen to sound coming from a screen. Edison told Henry Ford to give up making cars and work for him instead and make millions.
