A long time ago, I used to mentally berate other writers' bad writing habits like repeats and over-use of adverbs or weak adjectives, etc., but general readers don't notice these things. They just get on with it. And with that in mind, my attitude has significantly altered. I don't care what other writers do anymore, I just focus on my own prose, because that's the only writing I can influence.
Very good sentiments, and welcome to the chrons forums, Kev Heritage.
