'Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.' [Th. A. Edison]
'My grandfather once told me that there are two kinds of people; those who do the work and those who take the credit.
He told me to try to be in the first group; there was less competition there.' [I. Gandhi]
When I studied General Economics, my professor in Macro Economics (Huisman) once told us to be prepared to work in a completely different area after your graduation. Such an advice, given in a period of severe economic crises, I took literally by working in a wide range of fields. This gives many degrees of freedom when dealing with practioners, colleagues and students. Interestingly, technology is usually taken as a black box in economic theory, while today engineering is my primary focus and economics is a useful extra.
