So I did this for years when it came to starting my own YouTube channel and now my nostr.... whatever you want to call it.
I've literally helped people build their own channels and for some reason, never started my own.
So I started shooting handheld videos in my car. No editing, no reshoots, just raw, unedited thoughts. Now I'm doing several videos a week (quality will come in time) versus the zero of before.
Lower your barrier to entry. Figure out what is actually stopping you. For me it was my perfectionism, I know I can produce high quality video so I want to start there but I can't because they're are still things I need to learn, systems to build etc.
Find your Achilles heel and remove it.
