If you are going to be successful in creating the life of your dreams, you have to believe that you are capable of making it happen.
Believing in yourself is an attitude
Believing in yourself is a choice. It is an attitude you develop over time. Remember, the past is the past. There is no payoff for blaming them for your current level of self-confidence. It’s now your responsibility to take charge of your own self-concept and your beliefs. You must choose to believe that you can do anything you set your mind to–anything at all–because, in fact, you can.
If you assume in favor of yourself and act as if it is possible, then you will do the things that are necessary to bring about the result. If you believe it is impossible, you will not do what is necessary, and you will not produce the result. It becomes a self-fulfilling prophecy.
What others think about you is none of your business
If having others believing in you and your dream was a requirement for success, most of us would never accomplish anything. You need to base your decisions about what you want to do on your goals and desires.
Surprise, surprise! Most of the time, nobody’s thinking about you at all! They are too busy worrying about their own lives, and if they are thinking about you at all, they are wondering what you are thinking about them. People think about themselves, not you.
