What a person can believe a person can achieve.  This means the first key to success is believing  that you can complete whatever goal that you set for yourself.  Remember if you think you can or you think you can’t you will be right.  Believe in your own ability and the ability of the  Holy Spirit to work through you to complete the job that the God has brought you to.  His plan is to bless you and to prosper you .  He will work even the most difficult situation for good in your life.  Sometimes the fires are what we need to humble us and makes us into what  we need to be.  Remember to speak positive words to yourself because we believe more of what we hear ourselves say than anyone else.  After all you are a child of God and should honor that position.  Change your thoughts and your world will change
