Here is a very brief outline of the key points that will help you achieve the highest levels of success. Look into the nearest mirror - the person staring back at you is the only person responsible for your success. No one else is the cause of your success or to blame for your shortcomings. Successful people take full responsibility for their actions. Smile back at your reflection.
Successful people are cheerful, optimistic, and forward thinking.
If you think you don't have anything to smile about, smile anyway. Positive thoughts drive out negative thoughts. Positive self-esteem is the foundation for success. Feel good about yourself and your abilities, achievements and potential. Don't dwell on your mistakes.
