Stoic Philosophy for Screenwriters Facing Rejection

I’ve been reflecting on how Stoicism could offer some practical tools for screenwriters dealing with constant rejection and creative blocks. It’s a tough industry, and sometimes it feels like you’re at the mercy of others’ opinions. Stoic ideas about focusing only on what you can control like your effort and your attitude seem really relevant. Has anyone here applied Stoic practices to handle feedback or dry spells in their writing? I’m curious about specific techniques that have helped you stay grounded and keep creating, even when things don’t go as planned.
