You must develop a sense of what you can contribute that goes beyond 1 company or organization. A career path today will likely involve moving from organization to organization, creating a picture of rising circles, rather than a vertical ladder. In fact, a vertical rise within one organization will very likely move you away from your strongest areas of competence.
So much for industry, my friends, and attention to one's own business; but to these we must add frugality if we would make our industry more certainly successful. A man may, if he knows not how to save as he gets, keep his nose all his life to the grindstone, and die not worth a grout at last.
