Sticking to the trading plan is also good to avoid unfavourable trade as changing plans in the middle of a trade Can really lead to a loss in trade.
This is a common mistake of new traders. They intend to lose money because they don't have 1 final decision everytime.
Best example is when they open their trade, they don't have a plan like how much is their willing lose on every trade, when is the stop loss, and what is target price.
Some don't have stop loss and they are hoping their entry will recover.
