Engage in one kind of business only, and stick to it faithfully until you succeed, or until your experience shows that you should abandon it. A constant hammering on one nail will generally drive it home at last so that it can be clinched. When a man’s undivided attention is centered on one object, his mind will constantly be suggesting improvements of value, which would escape him if his brain was occupied by a dozen different subjects at once. Many a fortune has slipped through a man’s fingers because he was engaged in too many occupations at a time. There is good sense in the old caution against having too many irons in the fire at once. — The Art Of Money Getting Or Golden Rules For Making Money By P.T. Barnum — 1912
