WHAT I have said in the last chapter applies as well to the professional man and the wage-earner as to the man who is engaged in mercantile business.
No matter whether you are a physician，a teacher，or a clergyman，if you can give increase of life to others and make them sensible of the fact，they will be attracted to you，and you will get rich. The physician who holds the vision of himself as a great and successful healer，and who works toward the complete realization of that vision with faith and purpose，as described in former chapters，will come into such close touch with the Source of Life that he will be phenomenally successful；patients will come to him in throngs.
No one has a greater opportunity to carry into effect the teaching of this book than the practitioner of medicine；it does not matter to which of the various schools he may belong，for the principle of healing is common to all of them，and may be reached by all alike. The Advancing Man in medicine，who holds to a clear mental image of himself as successful，and who obeys the laws of faith，purpose，and gratitude，will cure every curable case he undertakes，no matter what remedies he may use.
In the field of religion，the world cries out for the clergyman who can teach his hearers the true science of abundant life. He who masters the details of the science of getting rich，together with the allied sciences of being well，of being great，and of winning love，and who teaches these details from the pulpit，will never lack for a congregation. This is the gospel that the world needs；it will give increase of life，and men will hear it gladly，and will give liberal support to the man who brings it to them.
What is now needed is a demonstration of the science of life from the pulpit. We want preachers who can not only tell us how，but who in their own persons will show us how. We need the preacher who will himself be rich，healthy，great，and beloved，to teach us how to attain to these things；and when he comes he will find a numerous and loyal following.
The same is true of the teacher who can inspire the children with the faith and purpose of the advancing life. He will never be ＂out of a job.＂ And any teacher who has this faith and purpose can give it to his pupils；he cannot help giving it to them if it is part of his own life and practice.What is true of the teacher，preacher，and physician is true of the lawyer，dentist，real estate man，insurance agent - of everybody.
` The combined mental and personal action I have described is infallible；it cannot fail. Every man and woman who follows these instructions steadily，perseveringly，and to the letter，will get rich. The law of the Increase of Life is as mathematically certain in its operation as the law of gravitation；getting rich is an exact science.
The wage-earner will find this as true of his case as of any of the others mentioned. Do not feel that you have no chance to get rich because you are working where there is no visible opportunity for advancement，where wages are small and the cost of living high. Form your clear mental vision of what you want，and begin to act with faith and purpose.
