Golden Rule

The people who surround you--your support system--will determine how well you will build and maintain the self-confidence necessary for success. Why? They are the ones that are feeding your mind on a regular basis. Having self-confidence that will never fail is a manifestation of a strong mind. Anything we want to be strong in the future needs to be fed well in the present. An Olympic athlete that dines on milkshakes and candy bars will be a former Olympic athlete in no time. A delicate flower that dines on Coca-Cola and darkness rather than water and sunlight will be a dead flower eventually. The car that has sugar in its gas tank rather than premium petrol will not go. By the same token, your mind needs to be fed well to become a strong, confident mind. So, how do you build a strong support system that will help you

Remove "haters" from your support system. Haters are the polar opposite to those bring unconditional love to your life. Rather than reveling in your success, haters revel in your misfortune. Haters, if they were not so dangerous, would be pitiable people. They are miserable people who have already decided that they do not have the talent, drive or intellect to be successful. Sadly, haters have decided that their best hope for happiness is to sabotage your attempt to be great rather than stage an attempt of their own. They want as many people as possible to share in their misery. Haters are the biggest threat to your self-confidence and should be avoided at all costs.
Be your own best friend. How do you become a better friend to yourself? Anyone who wants someone else to do well will start by putting him in the best position to succeed. Great leaders work to create an environment around those that follow that is conducive to success. Similarly, being your own best friend means positioning yourself for success as you accept the challenge of greatness. Know yourself like you wrote the manual. Use this knowledge to perform under the best circumstances possible (i.e., if you are a morning person, scheduled  big "events" for the morning when you can). Find ways to use negative people as motivation, not reason to fail.
By surrounding yourself with the right support system, you will be well on your way achieving the success that you deserve
