This is from the book  ‘Think and Grow Rich’  by Napoleon Hill ( published in 1937)

1. I know that I have the ability to achieve the object of my Definite Purpose in life. Therefore I demand of myself persistent, continuous action towards it attainment, and I here and now promise to take such action.

2. I realize the dominating thoughts of my mind will eventually reproduce themselves in outward, physical action and gradually transform themselves into physical reality. Therefor I will concentrate my thoughts for 30 minutes daily upon the task of thinking of the person I intended to become, thereby creating in my mind a clear, mental picture of that person.

3. I know the principle of autosuggestion (repeating and affirming) that any desire I persistently hold in my mind will eventually seek expression through some practical means of attaining the object. therefore I will devote 10 minutes daily to demanding of myself the development of elf confidence.

4. I have clearly written down a description of my Chief Aim (goals) in life. I will never stop trying until I have developed sufficient self-confidence for it’s attainment.

4. I fully realize that no wealth or position can long endure unless built on truth and justice. Therefore I will engage in no transaction that does not benefit all whom it affects. I will succeed by attracting to myself the forces I wish to use and the cooperation of other people. I will induce others to serve me because of my willingness to serve others. I will eliminate hatred, jealousy, envy, selfishness, and cynicism by developing love for all humanity because I know that a negative attitude towards others can never bring me success. I will cause others to believe in me because I will believe in them and in myself. I will sign my name to this formula, commit it to memory and repeat it aloud once a day, with full faith that it will gradually influence my thoughts and actions so that I will become a self-reliant and successful person.

Inspiring poem:

If you think you are beaten you are,
If you think you dare not you don’t,
If you like to win but you think you can’t,
It is almost certain you won’t.

If you think you’ll lose you’re lost,
For out of the world we find,
Success begins with a person’s will-
It’s all in the state of mind.

If you think you’re outclassed you are,
You’ve got to think high to rise,
You’ve got to be sure of yourself before
You can ever win a prize.

Life’s battles don’t always go
To the stronger or faster man,
But soon or late the one who wins
Is the one WHO THINKS HE CAN!
