I read on this page financemagnates, although it's been a long time but I think the points on the page can be a consideration for us before trading. besides that I am interested in the second point where Consistency and calmness are the most important things in this case. because in my opinion if we can't be consistent it might be difficult to run it or maybe we can run it but it tends to be more towards not focusing.

besides that in this case we must be able to pay attention to finances too, I myself will trade if my finances are stable in other words I will not force myself to trade if my finances are not stable.
and indeed we should have a plan but that doesn't mean when we are going to trade this can make us get profits that can make us stable in the long term of course that is not true like the second point you conveyed. therefore we need time to approach to find out which strategy is good and suitable for us and in my opinion this can involve our own circumstances.
and I agree with what you said, we must be able to avoid or control our own emotions. Of course, if that happens, it can make us experience overtrading which should not happen or excessive trading which instead of wanting to make a profit actually makes us lose money because self-control is also lost.
