How should actors think about building a social media following?
Use social media as a tool but don't let it become the main focus — treating it as the priority stops being fun and doesn't actually help your career, per advice from Eric Bana relayed by Julian.
How can actors practice their craft outside of auditions?
Do vocal warm-ups and exercises solo, treat self-tape auditions as practice reps, and consider the Jake Gyllenhaal method of repeating the same scene differently each time with a partner giving no feedback other than 'do it again, differently'.
Should actors only read the scenes their character appears in?
Read the entire script as an audience member first, since you can learn a lot about your character from what other characters say about them even in scenes you're not in; TV actors who skip this tend to get lazy.
What is the fundamental rule for doing improv?
Always 'yes, and' — accept whatever information your scene partner introduces and build on it rather than contradicting it, which keeps the scene moving and doesn't make your partner feel foolish.
How do you deal with ongoing family negativity or unsupportive comments about your career?
Have the harder, vulnerable conversation directly with family rather than avoiding it or resenting it silently; tell them plainly that you feel unsupported, because people often won't volunteer that and need to hear it to understand the impact.
How can you quiet self-consciousness while performing or in conversation?
Rather than trying to get everything right, intentionally allow yourself to 'get it wrong' or be spontaneous instead of planned; relaxing into trust in yourself reduces the hyperfocus on self that causes self-consciousness.
