Notebooks can help us to record mistakes or events that occur, so that we can look at them afterwards to remind us, for example, of something we shouldn't do, and sometimes even though we have written it down and read it, we sometimes still make the same mistakes, and this is basic human nature. . However, if we can manage it, it will not only have an impact on our way of trading, but will also carry over into real life, we will be wiser in facing life.
Indeed that mistakes can still occur sometimes and I think it's fine as long as most of the times we are doing the right thing. That should be enough as a compensation. It is only wrong if we use the " it's a human thing " as an excuse and will not try hard anymore in order to improve our selves. Better if we quit the risky activity that we do like for example trading because it will only help us to become more poor or problematic later on, if not now.
It is true that what we do on a certain thing, will also have impact on our general life, but if we already know our characteristics, it'll be easier for us to decide as well if we will venture this or that thing.
