I know this may sound somehow impossible for some, but really, to be successful in trading, you need to have the mind of a machine. Now, you cannot have this if you do not have a strategy and you cannot have a strategy if you do not take your time to learn.
Let me explain myself better, for instance, when using trading robots, you input your strategy, and they do it better because there is no emotion attached to it, except that they just do exactly what they are programmed to do. You cannot do well without a strategy and you cannot do well too when you keep changing strategies over and over again.
Learn, get a strategy, build on it, and then trade it like a pro. It is imperative that you get to see trading as a profession, which would always make you to see yourself having to let your strategy play out than letting your emotions rule you, which I believe most new traders are guilty of.
What makes you even better than a machine is the fact that you can think, you can fine tune your strategy with experience you keep gaining over time, but when it comes to never letting your emotions come before your strategy, you need to be like a trading machine.
In the first place dude, We are not a robot. I'm not saying your wrong about you mentioned in the above, but all of what you just said is not that easy. As a traders We really, really need time to spend with learning. You cannot learn it in one day only, you heard it now, and then tomorrow you know all, of course its not like that.
