You seem to have the right framework in mind for your strategy: your use of fundamental and technical analysis seems to be a good fusion of these two schools of thought. Despite this, I disagree with a number of conventions put forward by Julian Dawson as they would have prevented me from owning a few of my greatest-returning investments.
One matter which you appear to be mistaken with is the idea that once your strategy is laid out, then you should be set. I've been a stock market investor for many years and am still continuing to perfect my strategy. Your approach to investing shouldn't be a "set-and-forget" matter; but rather mistakes, successes and countless investment books will constantly change and ultimately improve your investment philosophy.
