"Concentrate your energies, your thoughts and your capital. The wise man puts all his eggs in one basket and watches the basket"

In this quote, Andrew Carnegie is stressing the importance of focus and concentration. He recommends people to direct their energies, thoughts, and capital towards a specific goal or endeavor. By doing so, one can maximize their potential and increase their possibilities of success. The expression "putting all his eggs in one basket" suggests the concept of investing all resources and efforts into one endeavor, rather than spreading them thin throughout multiple pursuits. This technique, according to Carnegie, is the mark of a sensible person who thoroughly monitors and protects their investments. In general, the quote highlights the value of tactical thinking and purposeful action in attaining success.
