Lesson number one is consistency! For over 25 years, I have been consistent in my approach and discipline. This is so very important. Don’t be a fundamentalist one week, and a technician the next. And don’t follow indicator A one month and switch to indicator B the next. Find a good method, be disciplined, and stick with it. If it doesn’t regularly beat the market, then get a new method. But be absolutely disciplined and don’t ever abandon a successful method because you think this time things are different.
