I don't like very much Lewis Cass' legacy but this quote sounds quite refreshing to me. It means for me 'people could talk about what you say, they could talk about what you dream of, as well. But in the end, only what you do really matters'.
I'm doing something inconceivable for the big majority of people I know and, to be honest, also for the big majority of people I don't know. Choosing a new life, a new career, a new country, a new language without having safety, an 'emercency exit' and so on is a very disturbing and disquieting thought. But it's also very stimulating and exciting: so many occasions, so many possibilities, so many doors to open!
Thanks for this quote, Mr. Cass.
