A very nice tweet thread by Christopher McQuarrie. It’s well worth reading the whole thread.

…After twenty five years in the craft, I’ve learned the secret to making movies is making movies - starting with little movies no one will ever see.

The secret to knowledge is doing and failing - often and painfully - and letting everyone see.

The secret to success is doing what you love, whether or not you’re being paid. The secret to a rewarding career in film (and many other fields) is focusing entirely on execution and not on result.
