The Man Who Thinks He Can, originally known as "Thinking", is a poem by Walter D Wintle that has inspired millions and been quoted my many authors.
The poem was referred to by Napoleon Hill in his 1937 book Think and Grow Rich, published by The Ralston Society.
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 fellow's will
It's all in the state of mind.
If you think you are 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 man who wins
Is the man WHO THINKS HE CAN
The exact date of the first, original publication of "Thinking" is unknown.
Later sources gave this poem, which originally carried the title "Thinking", the title "The Man Who Thinks He Can" and "It's All In The State Of Mind". In recent years the title "The Man Who Thinks He Can" has been adapted as the (wrongfully) assumed correct and original title. Of course "Thinking" remains the only original and correct title of this mystery marked poem, written by a great but little known poet.
