If we're all just trying to trade the probabilities while our various emotions and cognitive biases try and get in the way then the inevitable failure to do that usually means we end up trading our emotions and fears instead and the market takes us for an unpleasant ride.
To successfully get around that you have to find your own way of trading around your emotions. If most real risk (if not all of it) comes from not knowing what you're doing then you can mitigate that risk or eliminate it with enough knowledge and experience of your particular market, but people don't usually like getting their hands dirty and venturing too deep into the behavior of their own market. Even though that's where most of the edges are actually hidden!
There's an overkill of good advice in this thread alone, let alone on the forum as a whole, but it's not like one can just flip a switch and instantly apply some of it, that is why people offer advice in the first place
Just saying that if you don't yet know where your edge is coming from or whether you even have one, it would help to properly learn how to frame your trade and think probabilities instead of emotions and fears, meaning you know exactly what you're looking for and you know whereabouts to enter and exit in advance, based on whether you're right or not, and ideally you want the reward to be bigger when you do get it right compared to the punishment when you get it wrong.
If you took the time to truly break down all of the skills that you're trying to learn all at once (!!) then you'd probably realize why it feels so overwhelming at times and that maybe the best way to approach trading at the start is to keep it as simple as possible (K.I.S.S.), and build from there, having one rock solid foundation is more than enough to keep building further.
(well, maybe a little)
