How do I find my own creativity after years serving others'?

You can shape raw footage into something that genuinely moves people, and after years alone in the dark serving other people's visions, you are wondering where your own stories went. That question is not idle. It is the quiet voice of a maker who has given so much to others' work that his own got shelved. The stories did not leave. They have been waiting while you built your craft on everyone else's material, and that craft is now yours to spend however you choose. All the skill you poured into others' visions can serve your own the moment you decide to point it there. Start small and start now, before more years pass: one short thing that is yours, cut from your own idea, however rough. You do not need permission or a budget or the perfect concept. You need to begin, so the maker in you remembers he still gets to make. Your own stories are still there. Go tell one.
