Working 24 hours a day isn't enough anymore. You have to be willing to sacrifice everything to be successful, including your personal life, your family life, maybe more. If people think it's any less, they're wrong, and they will fail.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

I haven't gotten jobs because I'm famous or I have a big Twitter feed - it's primarily directors. People employ me because I'm right for the part. But then, everybody needs a bit of luck, being in the right place at the right time. You just gotta be in that place for that opportunity to come by.
