I can make my home office space as comfy, cool, great as possible, but I just physically can NOT get myself to start on my creative work at home. I write, so depending on your craft, this can be different, of course.
I like to go to a park/green space with a notebook for idea generation, then a cafe to lock in and get a draft done. If I'm stuck on something, I go for a walk with a thematic playlist to see if I can work it out in my mind before going back to the page.
All of this to say - I need to be out of my living space. I have notes on notes on notes of ideas, excerpts, etc. but as much as I think about getting started, I find ten things I have to do at home (and sometimes, I just sink into a video game).
My advice is less about overcoming something, and more just getting outside of your space and going somewhere else with the express intent on Getting Started.
Everyone works differently, so find the flow that works for you, but going to a new place with this intent gets the brain working (I think, anyway)
