Andrew Carnegie on Strategy

Here is the prime condition of success: Concentrate your energy, thought and capital exclusively upon the business in which you are engaged. Having begun on one line, resolve to fight it out on that line, to lead in it, adopt every improvement, have the best machinery, and know the most about it.

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

- Andrew Carnegie, famous American industrialist and philanthropist
