As long as we are still beginners, this is not an important problem because we can turn mistakes into very important experiences. The hope is that when we have experiences like this, in the future the same mistakes will not be repeated. Those who are currently professional traders certainly have a lot of experience from various kinds of mistakes they have made in the past.
I think it's kind of funny that for the first time ever, I'm posting my third reply on the same thread. Even though I know there's nothing wrong with that, I usually respond late anyway. Why are mistakes important? Most people give suggestions or recommendations, but they don't always follow them themselves—they just pretend to be pros. These mistakes make them realize they should practice what they preach. I've encountered many members like this, and I've made similar mistakes in the past.
When managing live trades, I used to tell everyone never to go all in. But early on in the forum, I was probably an SR member, and there was a coin I was highly bullish on because of YouTube influencers and the hype wave. At that time, I ignored all my trading rules and adopted an all-in strategy. It ended up being a waste of time and funds, with only a pretty average profit in the end. The most valuable lessons come from our blunders and mistakes, but only if we really acknowledge them and implement the learnings in our plans of action.
