Trust and Believe in Yourself

My favorite rule is for people to trust and believe in themselves. In order for people to trust and believe in themselves I feel they must trust and believe in God. I believe that trust and believe actually go hand and hand because if people will believe in themselves they can trust themselves. Think about it this way, if people do not believe in themselves who else is going to believe in them and if they do not trust themselves who else is going to trust them. People tell others that "they can be anything they want to be in life". But what they do not tell them is that they have to first believe they can be anything they want to be in life. Just saying to themselves that they can be anything they want to be is not going to make their ambition come true.  Do all people think that they can trust and believe in themselves? If not, think about this verse from Psalm 9:10, And they that know thy name will put their trust in thee: for thou, Lord hast not forsaken them that seek thee.
