If I had to give you one piece of advice, it would be this: don’t be intimidated by other people’s opinions. Only mediocrity is sure of itself, so take risks and do what you really want to do. Seek out people who aren’t afraid of making mistakes and who, therefore, do make mistakes. Because of that, their work often isn’t recognized, but they are precisely the kind of people who change the world and, after many mistakes, do something that will transform their own community completely.
