You’ll meet a lot of people, who, to put it simply don’t know what they are talking about.
In 1970, a CBS executive famously said that there were four things you would never ever see on television:
A divorced person, a Jewish person, a person living in New York City and a man with a mustache.
By 1980, every person show on television was about a divorced Jew who lives in New York City and goes on a blind date with Tom Selleck.Develop your own compass and trust it. Take risks. Dare to fail.
Remember the first person through the wall always gets hurt.
Aaron Sorkin (May 13 2012, during commencement speech at Syracuse University)
The speech is well-worth listening to in its entirety.
