This answer says nothing about what you tried. “Create a habit” also mostly isn’t a one-shot solution in the way the OP uses the term.
My relation to the article was in reference to implementation (of a habit) and to address the 0.1% in changes that advocate for a better outcome for a solution to change. I play tennis and I must also sharpen this skill with complementary solutions (ballet) to ensure I win my matches. Again, it’s about the small solution changes that add to a whole.
