The connection you've made between the soil and your life conditions for creativity is so appropriate.
And you're right; what each person will need to do to create those conditions in their own life is different.
I've realized recently that I haven't been "filling the bucket" as some people say. I've been writing and that's just about it. And that has its consequences. I need to get back to investing time in other things that I enjoy and that ignite that creative spark. (Admittedly, I do find it a bit easier said than done.) Regardless, it's important!
