However, if only with instinct and no risk management, the level of possibility of loss will be much higher. It is better to be careful when trading, don't just rely on instinct.
failing to prepare is preparing to fail
Indeed, I remember the words of Benjamin Franklin's quote, which is essentially like that. And that's what happened, because preparation is part of our success in the future. We must also remember this quote:
"Success is the result of preparation, hard work, and learning from failure" — Colin Powell
This is why in every endeavor, preparation, hard work in action, and also evaluation from learning from failure, are very important, and learning from experience is also very helpful. Especially in trading or investment, this is very necessary, to manage risk better.
