Although, emotions are necessary for almost everything, it could be disastrous if it overwhelms or over clouds our judgements and thus leading to wrong decision making. We need our minds to be stronger than our emotions at all times or else we loose every time.
Most times were emotions clouds our judgement are mostly in relationships, times when we are in love or matters concerning families or friends. Most times we know we make a wrong decision but we are okay with it because our emotions are on the line.
Firstly, we should learn the concept of objectivity and it's necessities and advantages.
Secondly, in cases where we are to make decisions that involves emotions, such decisions should be given to a third party.
Thirdly, for those in relationships who gets heartbroken easily, your minds should be trained to the points where it accepts anything and rejects the idea that every relationship is a fairy tale.
