To get what you want from life you have to believe in yourself. You have to believe that you can do it, regardless of what it is that you want.
Believing in yourself is, as Canfield states, a choice. While we could get into a conversation that our past, how our parents parented us, had an impact on us, there is no benefit in such a conversation. To transform our life we have to take responsibility for our thoughts and beliefs, especially those we have about ourselves, about our past and self esteem. It is our choice to continue to believe and think the way that we believe and think.
Given that what you think and even say is important, you need to be present to about the words you put out into the world. For example, in believing in yourself, you have to give up saying, “I can’t.” Saying or using “I can’t” will limit you, will cut off possibility, will cut off possibility from your life. The work of watching your word is your total and complete responsibility.
Simply decide that you can or are able to do anything you want. Choose to believe that you are capable of doing what you want and begin to work towards it, take action. It is, as Canfield also states, a matter of attitude.
Having others believe in me can be of help to me, as support for example. However, it is not necessary for me to fully believe in myself. What is important is what I believe, what I believe about myself and more specifically having the belief that I can do what I want. This choice is mine.
