It's very funny that traders want to archive extra ordinary results with ordinary mindset. Trading is not easy. 'It's not suppose to be easy. Anyone who finds it easy is stupid.' - Charlie Munger.
To archive great success you need a higher level of reasoning, you need to go beyond the norm. Average traders will make investment decisions without reasonable conclusions; they follow simple indicators and the hope for some magic. That why they often lose.
Trading is complex, you can't be making buying or selling decisions on the fly. You need to do your research, you have to gather as much information as you can about the asset. Normalize spending time learning about an instrument you're investing in. Always take a trade as if it's your last opportunity. If you're not sure of your analysis; don't invest. If you don't have clear reasons to beck your decisions, don't invest.
Markets are not fixed, therefore your thinking shouldn't be. It's important to adjust your trading methods according to the behavior of the market, This means that you have to watch your trading method very careful, you have to analyze not only the market but also how your method or strategy behave in different markets and circumstances. If you see your method no-longer giving you the desired results; it might be time to adjust.
