So, what you're getting at is, don't let your emotions run the show. We've got a strategy or game plan to stick to, and we can't allow our feelings to take the wheel. That's why we have these popular terms like FOMO and FUD - they're all about investors and traders making decisions based on their emotions.
He was just elaborate the meaning but indeed the main thing is never allow yourself to controlled by emotion because this will not let you decide correctly , we will even have bad looks at how the market moves in particular ways.
and also try to always use Bot as Stop/Loss is what we can have for safeties if we cannot monitor our trading and investments.
We must take into account that not all who try trading become successful, some have also had a terrible experience and still, they continue trading.
For me, I don't think we need to sacrifice our finances knowing that we failed in trading, I think we should also know the words stop and quit if the the situation is not really in our favor. In fact, it was not a big deal if we failed and thought that some people would laugh at us but it was a big issue when we lost a lot of money and committed debt.
I can attest to that mate as I am also a trade loser from the past , even lose multiple times when I am starter but never that i lose my faith , and since I was not lucky in day trading , I focused in Holding and indeed , success is what i gain for years now.
