"there are two very different types of optimism"

"The practical insight is that there are two very different types of optimism. Complacent optimism is the feeling of a child waiting for presents. Conditional optimism is the feeling of a child who is thinking about building a treehouse. “If I get some wood and nails and persuade some other kids to help do the work, we can end up with something really cool.”
.
What the theory of endogenous technological progress supports is conditional optimism, not complacent optimism. Instead of suggesting that we can relax because policy choices don’t matter, it suggests to the contrary that policy choices are even more important than traditional theory suggests."

Faz-me recordar:

"O presidente de uma associação não pode e não deve falar impunemente. Deve ser consequente, deve ser responsável. Não deve mentir mas deve dar esperança. Não esperança cor de rosa, não esperança mágica mas esperança com base nas oportunidades que possam existir."
