From what I think, I believe the first thing you should do as a trader is to make sure your analysis is correct. I have seen someone trading with stop loss before and he keeps on losing money, let's assume he enters a trade and he set his stop loss at - 10% of his capital immediately the stop lose as being triggered, he will enter another trade again and he will set stop loss at - 10% of his capital, the stop lose was triggered again, that was how he was losing his money gradually, am not saying stop lose is bad but we should always make sure we do our analysis well first. whenever am trading I don't really use stop loss but am always online to monitor my trade myself, I don't really believe in stop loss but I don't discourage people from using it.
I think what he mean by taking risk on our own way is we go on our own and we don't follow what is commonly suggested. If we are a starter and have less experience then we shouldn't be hard headed but we must follow what the elders are saying because they already have an adequate experience on this market.
Analysis is essential in trading but I think this isn't the first thing that we should learn as a beginner. There are more important things than this. The reason why is because analysis can still fail no matter how sure you are. Stop loss on the other hand, is not a magical tool to help us prevent from losing but it can work like a charm as long as you already know how to use it the proper way.
