If it came early enough and you loved life as much as you loved your work it would take much character to resist the temptations. Once writing has become your major vice and greatest pleasure only death can stop it. Financial security then is a great help as it keeps you from worrying. Worry destroys the ability to write. Ill health is bad in the ratio that it produces worry which attacks your subconscious and destroys your reserves.
