You should turn around at the end of the day and say I really like that piece of work, or that piece of work sucked. Not, was that popular or wasn't it popular?
Knowing what I do now, I don't know if I'd ever have the balls to go to film school, with no connections and no knowledge of the business side at all.
And I know that sounds outrageous, but it's true. Such monopolies as Google, Facebook, Amazon, Apple are trying to stay with us from the moment that we wake up in the morning until the moment that we go to bed at night. They want to become our personal assistants. They want to become the vehicles to deliver us news, entertainment, to track our health. They want to obey our every beck and call through Amazon Alexa and Google Home.
