I think that image of a tortured genius (alcoholic, depressive, pariah is 1/100 like a Hitchens or Poe) that we romanticize when in reality, all great works of humanity have come through consistent toil and accident.
Most people ask Ryan Holiday to review their writing since they are a “bad writer” but his biggest complaint is they have nothing to show him.
Also, great masters always have a stimulating hobby like Einstein (violin) or Tolstoy (chess). This allows their mind to actually find new ways of attacking their task subconsciously.
I would recommend the book, “Mastery” by Robert Greene. I guess if you are on the older side of 30, then find someone who is where you want to be in 10-15 years (a writer) and ask them for an apprenticeship.
If you have a family, then you will have to accept the fact that if writing is what you really want to do (and we’re meant to do it), then you can have no resting time.
Just don’t give up, you are a wordsmith (takes more to be a great writer, I know).
