We agonize over decisions and deliberate if something makes sense for us or not. When we cannot arrive at a decision, it is worth considering our hesitation and why.
Inevitably, we may want to listen to our innate senses when we cannot decide. For example, the person you were looking to hire does not seem right. The transaction you are considering looks a little concerning. The new position you are contemplating is daunting, the expense, the relationship, and so on.
Suppose it is an important event and significant to your being, and even in some minor cases, we should genuinely listen to our senses. If it is not unequivocally absolutely yes, it very well is a definitive no. So cut your losses and move on.
In a world of almost 8 billion people with infinite possibilities and opportunities, this one is just not for you.
