Fashion Statement #7
O (meu) truque este inverno são os lenços ... para além de serem giros e darem pinta, dão imenso jeito para aconchegar o pescoço com frio e tirar em sítios mais quentes ...

Sentido de orientação
(se) parece conversa de doidos (então é porque provavelmente é) mas a verdade é que gostei de andar perdida. Isto de se ser orientada, conseguir encontrar atalhos e andar por todo o lado tem as suas desvantagens - há poucos sítios por descobrir. Por isso hoje deu-me especial prazer andar perdida por sítios nunca explorados à procura ...afinal:
When was the last time you did something for the first time?
Custo afundado
Esta é uma teoria de gestão de que o meu hubby me falou no outro dia aplicando-a "à vida real":
"In economics and business decision-making, sunk costs are retrospective (past) costs that have already been incurred and cannot be recovered. [...] In traditional microeconomic theory, only prospective (future) costs are relevant to an investment decision. Traditional economics proposes that an economic actor not let sunk costs influence one's decisions, because doing so would not be rationally assessing a decision exclusively on its own merits. The decision-maker may make rational decisions according to their own incentives; these incentives may dictate different decisions than would be dictated by efficiency or profitability, and this is considered an incentive problem and distinct from a sunk cost problem.
Evidence from behavioral economics suggests this theory fails to predict real-world behavior. Sunk costs greatly affect actors' decisions, because humans are inherently loss-averse and thus normally act irrationally when making economic decisions.
Sunk costs should not affect the rational decision-maker's best choice. However, until a decision-maker irreversibly commits resources, the prospective cost is an avoidable future cost and is properly included in any decision-making processes. For example, if you are considering pre-ordering movie tickets, but have not actually purchased them yet, the cost remains avoidable. If the price of the tickets rises to an amount that requires you to pay more than the value you place on them, the change in prospective cost should be figured into the decision-making, and the decision should be reevaluated".http://en.wikipedia.org/wiki/Sunk_costs
Ou seja, esquece as perdas e não as consideres nas decisões futuras, considera-as um custo afundado, com a vantagem de que pelo menos (espera-se) se tenha aprendido no caminho....
