There are musicians who have remarkable talent, and who yet remain poor. There are blacksmiths, carpenters, and so on who have excellent mechanical ability, but who do not get rich. And there are merchants with good faculties for dealing with people who nevertheless fail. The different faculties are tools. It is essential to have good tools, but it is also essential that the tools should be used in the right way. One man can take a sharp saw, a square, a good plane, and so on, and build a handsome article of furniture. Another man can take the same tools and set to work to duplicate the article, but his production will be a botch. He does not know how to use good tools in a successful way.  

The various faculties of your mind are the tools with which you must do the work that is to make you rich. So it will be easier for you to succeed if you get into a business for which you are well equipped with mental tools. Generally speaking, you will do best in that business which will use your strongest faculties — the one for which you are naturally “best fitted.” But there are limitations to this statement also. No one should regard his vocation as being irrevocably fixed by the tendencies with which he was born. You can get rich in ANY business, for if you have not the right talent, you can develop that talent. It merely means that you will have to make your tools as you go along, instead of confining yourself to the use of those with which you were born.
