Trading tends to bring out all kinds of emotions - hope, anxiety, greed, despair, joy etc. The worst is Regret because this mental state is like a void that sucks you in. It kills your confidence and makes you indecisive. When you become indecisive, you tend to make the wrong decisions which leads to more regrets and the cycle continues. So to overcome this, you need to let go of every bad decision you made and stay focused on what you aim to accomplish next. This is how I program my thoughts and move forward.
