I think the most important thing to become a trader is to control your emotions. Many new traders often let their emotions overwhelm and they often make the wrong decisions. If you have negative thoughts while trading, it is best to stop and resolve those emotions before returning to your trade.
This is the most importanf thing for me, because with this it can change everything, we can win or we can lose, a proper mindset is needed for us to make a right choice in everything. Trading and gambling needed a healthy mind so that we cannot lose our money just because of our emotional capability. This must be considered.
Focus is what we need and it follows a positive mindset. Anyhow, emotions are the rival thing in trading and you'll certainly out from focus if you allow these emotions controlled us. Handling these things is a step by step, you can't go over the top without struggling difficulties and have it settled down pretty quick will absolutely help us out from suffering big losses and get what we aim for.
