Fernando Pessoa worked as a translator and commercial letter editor, advertiser, and copywriter, while also trying his luck as a publisher, pioneering inventor, and entrepreneur.

The poet of "The Keeper of Sheep" and "Triumphal Ode" wrote simultaneously astute and enjoyable texts in which he analyzes various theoretical aspects of the economy. He explains in a simplified and lively manner what free competition, government control, monopoly, civil servant, etc., mean and articulates practical advice with precision.

He could rightly be awarded the title of the poet of economy and commerce.
