Nice experience you have but I have different opinion. Not healthy because we always ignore our rules and avoid stop loss & take profit area ( greedy ). Only those things become our failure but i'm afraid many people always repeat it again. Have disciplines and believe with our skill is very important, no success with out ignore rules. I hope every one stay focus and disciplines with their rules.
This is an interesting point and most likely you are right, trading is already very stressful as we know but traders make it even harder for themselves because they do not even follow their own rules, I know this is the case because I have done that mistake myself, and when everything goes right then you think of yourself as a genius but when things go wrong, which is most of the time and that is why you have those rules in the first place, you begin to regret your decisions and to doubt your own judgment.
So if we want to make trading easier for ourselves we need to have a very precise strategy about what we want to do in the market and how we're going to accomplish it and even more importantly we need to follow that plan.
